By pre-calculating the digests we can manually construct the emoji URLs,
removing the need for using Rails' asset URL helpers. The reason we
don't want to use these helpers for Emojis is two-fold:
1. Rails' image_url() method is slow, really slow. For one it _might_
have to calculate digests but it also performs a lot of other
intensive operations (judging by the source code and based on
measuring timings).
2. We have a lot of Emoji which coupled with the above can result in it
taking minutes to load Emoji autocomplete data.
Using this pre-calculation setup generating the digests takes around 7
seconds (including the time it takes to start Rails/Rake), and only
around 600 milliseconds to load _all_ the autocomplete data of a project
(measured locally).
This commit _does_ change the Emoji URLs from absolute to relative URLs
as these are much easier to generate.
To update the Emoji data simply run:
rake gemojione:digests
Then commit any changes.

This was previously possible through the API but can now be done
through the project#edit settings screen if the current user is
the owner of the project.
Update changelog
Notifications button was unavailable if user wasn't member of the
project, even if protected project is available via group privileges.
Showing disabled button with explanation tool-tip is less confusing.
This closes#2846.
