Add capybara-screenshot gem

This is a handy little gem that automatically saves the page and a screenshot when a Capybara test fails to `tmp/capybara/` so you can easily see why it might have failed without adding your own `save_and_open_page` directive in the code.

Also reduces the timeout for Capybara tests when not in a CI environment.

See merge request !578

Get Gitorious importer to work again.

Fixes #1504.

See merge request !576

Use Projects::CreateService to fork projects so that after-create hooks are run.

Makes for cleaner code and less duplication, and causes the "User created project Namespace / Project" event to be posted and system hooks to be run.

See merge request !575

Minor design change grab-bag 🎉

I started with one simple change and found a few more, so here they are.

### Simplify icon style selectors

All FontAwesome icons have an `fa` class, so just use that.

### Don't override color of code blocks in notes

This was a pet peeve of mine.

### Items with tooltips don't need a 'data-original-title' attribute

This attribute gets added dynamically by Bootstrap's tooltip JS based on the `title` attribute

### Fix Profile > Design live-updating

`ui_blue` wasn't added to the list of classes to remove, so if a user changed to that theme, any subsequent changes wouldn't be live-updated.

This change refactors Gitlab::Theme a bit to make it harder for this to happen in the future with new themes.

### Remove the `has_bottom_tooltip` class

Bootstrap's tooltip JS can read the placement from a `data-placement` attribute.

Further, when we supply the `selector` option to `tooltip`, tooltips will be added to any dynamically-added elements matching the selector, without us having to re-call the `tooltip` method.
