Revert "Merge branch 'fix_email_images' into 'master'"

This reverts commit d66148ef, reversing
changes made to cdb64a81.

This change needed to be reverted,
because not enough email clients support inline images.

/cc @DouweM As discussed before. I'll try to create a MR to allow access to all images this week. I'm a bit busy at the moment so no guarantees. ;)

fix stuck MR

If `locked_at` is `nil` return that the merge has been locked long enough and those are old merges stuck in locked state.

Fixes #348. Related to 64874193.

See merge request !517

Remove the invalid key factories

They're only used once each, and they're easy to build in-place.

See merge request !1766

Speed up the overridden `link_to` helper

Only bothers to check the provided link's external status if it's a String that doesn't begin with a path or anchor character.

Seems that I deleted a bit to much with my last attempt to remove the failing test.
I've run the entire spinach suite again locally and it seems to pass.

Earlier today I accepted a MR that removed the redundant help link on the dashboard sidebar.
This MR removes the now failing test.

Explicitly set image alt to prevent graphical glitches

Rails image_tag sets the alt-attribute to the filename which causes graphical glitches if the file could not be loaded.

Fix issue9098 clean path

Allow admin to create public deploy keys that are accessible to any project.

Addresses private issue https://dev.gitlab.org/gitlab/gitlabhq/issues/1774.

Project settings:

![Screen_Shot_2015-03-27_at_14.46.48](https://gitlab.com/gitlab-org/gitlab-ce/uploads/01799ff912671ba6db3f828ea1aca1a6/Screen_Shot_2015-03-27_at_14.46.48.png)

The "Public deploy keys" section is only shown when there are any. If there are public deploy keys but no project deploy keys, only public deploy keys are shown. If there are no public deploy keys and no project deploy keys, the current "Deploy keys from projects you have access to will be displayed here" placeholder is shown.

The list of projects below the public key has been changed to only show projects the user has access to.

"Public deploy key" seems to be repeated on the left, but the first is just the title. The label is always visible for public deploy keys.

Admin index:

Projects using the deploy key are listed on the left and can be disabled easily.
