Improve BitBucket integration documentation [ci skip]

This MR will improve the BitBucket integration documentation by

- mentioning the need to reconfigure GitLab after changing the configuration file, if you're using the omnibus package.
- adding a section about configuring a Host entry for bitbucket.org.
- switching additional steps 1 and 2, because connecting to BitBucket will only work after you added the SSH key and the Host entry.
- using sudo for the ssh connection in step 2, so that it is more obvious, that the git account should be used to establish the connection.

Order commit comments in API chronologically

When fetching commit comments via API, the comments were not ordered,
but just returned in the order Postgresql finds them. Now the API always
returns comments in chronological order.

Same as !628 but with CI

Fix upgrader script

This is a fix for upgrader script not guessing the latest version correctly.

Upgrader now handles versions where a version part (major/minor/patch) can have multi-digit number, also ensures that the latest version is chosen from git tags by converting tag to Gitlab::VersionInfo and than selecting the latest/greatest version.

Fixes: #1476

Make namespace API available to all users

### What does this MR do?

This MR makes it possible for a user to query namespaces to which he/she has access. Also, it adds documentation for the existing API.

### Why was this MR needed?

Even though the `groups` API exists, it might still be useful to have an endpoint that tells the namespace type (e.g. `user` vs. `group`), especially if a user has access to a number of different projects.

### What are the relevant issue numbers?

Closes https://github.com/gitlabhq/gitlabhq/issues/9328

See merge request !708

Use entity number for plus sign in push emails

Was doing some testing today and found that both outlook and gmail had issues displaying the html content produced for push emails when a file was added.

This is how gmail shows it:
![Gmail_name](https://gitlab.com/stevenorman/gitlab-ce/uploads/24be115dbae97997bc02e2ec70d9870c/Gmail_name.png)

And this is for Outlook:
![Outlook_name](https://gitlab.com/stevenorman/gitlab-ce/uploads/4b5a54956139d36d78f9c61c83e99928/Outlook_name.png)

iOS devices work with the + entity, as does Mail on OS X, but I'm wondering if it is only available for newer html parsers (a quick browse on the w3c site seems to show that it was added in html 5).

Changing the entity to `+` and both gmail and outlook and iOS and Mail.

Omit link to generate labels if user does not have access to create them

On a project that has no labels, a user was provided a link to create labels on the "Labels" tab, resulting in a 404. This MR changes the next to "No labels created" if the user lands on this page but does not have permission to add a label.
