Support configurable attachment size in Application Settings page
### What does this MR do?
This MR provides the ability to configure the maximum size of an attachment inside a note. A parameter has been added to the Application Settings page.
### Are there points in the code the reviewer needs to double check?
What should be done with the legacy note attachment validation? I added code to make the validation work with the configurable setting. I could see an issue where an admin lowers the limit from 10 megabytes to 5 megabytes, which could cause an existing model to be invalid.
### Why was this MR needed?
We often have attachments that exceed 10 MB, and it would be nice to be able to override the defaults.
### What are the relevant issue numbers / [Feature requests](http://feedback.gitlab.com/)?
See Issue #1258

Addresses #1347.
Untested since I'm in a bit of a hurry. Will definitely have time to test and add unit tests before the 7.10 release :)

Don't allow username to end in period.
The current behavior doesn't do username referencing and mentioning in sentences like "I discussed with with @douwe." since `douwe.` is matched as a username.

For view port sizes between 1260px and 1200px pixels the event-title was
too wide, thus not truncated and got pushed into a second line.
100% - 174px was chosen as the max-width because 141px is the widest
.event-item-timestamp can get (with 'less than a minute ago') + 24px for
the avatar + 8px avatar margin + 1px to fit into the gap.
Unbind task item checkbox events and then rebind them
Fixes#1340
This issue was caused by this line: https://gitlab.com/gitlab-org/gitlab-ce/blob/master/app/views/projects/issues/update.js.haml#L17
`new Issue()` gets called on every JS-based issue update, and all the binds in the constructor get re-applied without first unbinding the existing ones. Right now my fix is *only* for the checkbox events, and I suspect there are similar issues still present for other events.
