Link to readme from description

If you are viewing a repository for the first time you are likely to view the description. If you want to keep reading after that you can now click a link to the readme. This place is in addition to the README button at the bottom of the right hand menu that is harder to find. If you have edit rights only the description edit button is shown to ensure the text fits, the assumption is that the readme is most interesting for people not yet added to the project.

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.

Why was this MR needed?
Sometimes there could be an import without getting any pushes all the time or for a long time. The size is only recalculated on a push.

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.

Are there points in the code the reviewer needs to double check?
No.

Why was this MR needed?
It is annoying that the title is updated while typing and never changed any more.
