Easy dev install

@jeroenvanbaarsen  just tried the following:

1. Removing therubyracer from gemfile
2. Install node (brew install node or sudo apt-get install nodejs)
3. Run $ spinach features/

All worked as before, so this would mean people have to install the node dependency on their local machine, but in my experience this is much easier than installing libv8, especially for non ruby-devs. /cc @jacobvosmaer

While loading the Rails app we cannot assume that the gitlabhq_xxx
database exists already. If we do, `rake gitlab:setup` breaks!

This is a quick hack to make sure that fresh development setups of
GitLab (from master) will work again.

event-last-push styling fix

When viewing a fresh install of GitLab on a mobile device after a branch with a name of sufficient length, the broken styling can be seen as follows:

I modified the css for .event-last-push and .event-last-push-text to make it look correct:

As this is a purely css change, I don't believe it will break any tests. The only occurrence of .event-last-push* is in ./app/views/events/_event_last_push.html.haml

See merge request !279

Forms action padding fix

The padding on the forms action is not adjusted based on screen width:

I added a media query for .forms-action at min-width: $screen-sm-min and moved the padding-left: 17% into it:

Full width padding remains as is:

As this is a purely css change, I don't believe it will break any tests. form-actions occur everywhere there are form actions.

Dashboard icon styling fix

When viewing a fresh install of GitLab on a mobile device, the styling for the dashboard item icon is broken in such a way that if the description div is more than 100px high, its contents wrap beneath the icon as shown below.

![Screen Shot 2015-01-05 at 7.11.37 PM](https://gitlab.com/uploads/cloudwindhk/gitlab-ce/9ac2feca33/Screen_Shot_2015-01-05_at_7.11.37_PM.png)

I modified the css for the icon and added a new class to the description div and now it behaves as expected as shown below.

![Screen Shot 2015-01-05 at 6.56.33 PM](https://gitlab.com/uploads/cloudwindhk/gitlab-ce/25cf3212d2/Screen_Shot_2015-01-05_at_6.56.33_PM.png)

As this is a purely html/css change, I don't believe it will break any tests. The only occurrence of .dashboard-intro-icon is in ./app/views/dashboard/_zero_authorized_projects.html.haml
