This MR adds configuration variable `email_reply_to` to make it possible to configure a custom Reply-To address other than the default `noreply@mydomain.com`.

### What are the relevant issue numbers / [Feature requests](http://feedback.gitlab.com/)?

#1305

See merge request !455

Link paths for http and ssh in the admin project show view are incorrect

The link paths for http and ssh in the admin project show view are incorrect. Clicking on them effectively reloads the page. I think the intent is to have the links point to the project dashboard.

Incorrect: http://gitlab.example.com/admin/projects/[namespace]/[project]
Correct: http://gitlab.example.com/[namespace]/[project]

Closes #1305

Changes the width of sidebar in issues and MRs when affix event fires

Fixes #1320

Width is set when Bootstraps affix event is fired and then removed when it reaches the top or bottom.

Exposing Project Labels in the REST API

The intent here is to expose the tag_list property of the Project entity over the REST API so that any project searches include the information. The specific reason I've implemented this change is for an environment in which multiple gitlab servers exist, where a central portal to the projects that are spread around the network will be useful. Having access to filtering on this fairly large project list based on their labels, will be of great use.

This satisfies the feature request http://feedback.gitlab.com/forums/176466-general/suggestions/6325819-project-labels-via-api

The change was made in the `lib/api/entities.rb` file.

The output of a `GET` to something like `/projects` or `/projects/7` is now:
```javascript
{
  "id": 7,
  "description": "Veritatis est eaque voluptas magni expedita.",
  "default_branch": "master",
  **"tag_list": [
    "typeahead",
    "twitter"
  ],**
  "public": false,
  "archived": false,
  "visibility_level": 0,
  ...
}
```

Fix and improve help rendering

Improve regexp to prevent false positives

If a filename happened to contain "db" and enough "rwx" characters before, then
this test would previously fail. For example:

```
drwxr-xr-x gitlab-runner/gitlab-runner      0 2015-04-02 07:46 uploads/tmp/cassidy.stokes8477/gitlabhq/36d972fa55d6b44810fc6fd843473adb/
```

Adding a space before the "db" match string tightens up the regexp and reduces the
chance of an unintended match.

Support configurable attachment size in Application Settings page

### What does this MR do?

This MR provides the ability to configure the maximum size of an attachment inside a note. A parameter has been added to the Application Settings page.

### Are there points in the code the reviewer needs to double check?

What should be done with the legacy note attachment validation? I added code to make the validation work with the configurable setting. I could see an issue where an admin lowers the limit from 10 megabytes to 5 megabytes, which could cause an existing model to be invalid.

### Why was this MR needed?

We often have attachments that exceed 10 MB, and it would be nice to be able to override the defaults.

### What are the relevant issue numbers / [Feature requests](http://feedback.gitlab.com/)?

See Issue #1258

Archive repositories in background worker.

Depends on https://gitlab.com/gitlab-org/gitlab_git/merge_requests/17 being merged, a new `gitlab_git` being released and this MR's `Gemfile.lock` being updated..

See private issue https://dev.gitlab.org/gitlab/gitlabhq/issues/2173.

To do after this is merged: Update https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/files/gitlab-cookbooks/gitlab/templates/default/sv-sidekiq-run.erb in omnibus.

Don't allow username to end in period.

The current behavior doesn't do username referencing and mentioning in sentences like "I discussed with with @douwe." since `douwe.` is matched as a username.

Addresses private issue https://dev.gitlab.org/gitlab/gitlabhq/issues/2174.

Ability to skip some items in backup

https://dev.gitlab.org/gitlab/gitlabhq/issues/1936

Now it is possible to run

```
sudo gitlab-rake gitlab:backup:create SKIP=repositories,uploads
```

available options: repositories,uploads,db

See merge request !470

If a filename happened to contain "db" and enough "rwx" characters before, then
this test would previously fail. For example:

```
drwxr-xr-x gitlab-runner/gitlab-runner      0 2015-04-02 07:46 uploads/tmp/cassidy.stokes8477/gitlabhq/36d972fa55d6b44810fc6fd843473adb/

Unbind task item checkbox events and then rebind them

Fixes #1340

This issue was caused by this line: https://gitlab.com/gitlab-org/gitlab-ce/blob/master/app/views/projects/issues/update.js.haml#L17

`new Issue()` gets called on every JS-based issue update, and all the binds in the constructor get re-applied without first unbinding the existing ones. Right now my fix is *only* for the checkbox events, and I suspect there are similar issues still present for other events.

Don't use chmod_R for backup tars

When creating backup tar files, only change permissions on the `db`, `uploads`, and `repositories` directories, not their contents.  See https://dev.gitlab.org/gitlab/gitlabhq/merge_requests/1716#note_40472
