Issues filter by description

In Issues section of any project there is a filter box, which by default says 'Filter by title or description' - so this behaviour is desired. But in fact only filter by title works and filter by description DOESN'T work. This fix adds description fitlering.

Move Event Helper To Use Project-level IDs Instead of Global IDs

This MR fixes issue #303 by updating app/helpers/event_helper.rb to use project-level IDs within the event title as opposed to global IDs (i.e. use target_iid instead of target_id).

This ties the issue and merge request numbers on the feed together with the numbers used throughout the rest of the site.

Update repository size during import

What does this MR do?
Update the repository size during the import

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

Title fix for new SSH Key

What does this MR do?
Wait until the user "finished" his input in the key field (focus lost) before copying the mail part to the title.

It is annoying that the title is updated while typing and never changed any more.

Skip to buttons on tabbing in issues page

http://www.w3.org/TR/html5/editing.html#sequential-focus-navigation-and-the-tabindex-attribute

For tabindex:

```
If the value is a negative integer
The user agent must set the element's tabindex focus flag, but should not allow the element to be reached using sequential focus navigation.
```
