Postgres fix. Closes #175

Fix mobile menu after adding help link

After https://github.com/gitlabhq/gitlabhq/pull/6897 the mobile menu ran off the left side of the screen. I don't see much we can do to squeeze all the items into mobile's width. I think hiding one of the items is acceptable and which is a matter of opinion.  I suggest hiding the user's avatar on mobile but the search icon or help icon would both be options as well. Let me know if you want a different icon hidden on mobile.

Fixed misspelling

Improve issue and MR mobile UI

Improve the mobile UI for issues and merge requests. To make use of Bootstrap's column grid this also slightly alters the current desktop UI. Namely, the state box is slightly wider and is a 2-column width rather than being a fixed width. This makes it so we can easily break the row into 2 lines on mobile.
