fixed a number of bugs. beta testing for the canadian release continues (bugs are being fixed in dev)

Improved the directory column sorting. It handles different schemas (through mappings.yml) better. Emu was crashing on changing sort column. (commit, commit, commit)

Added exception_notification plugin, which can be customized for each country in their own branch. (Exception notification sends emails whenever the app crashes) Got rid of hoptoad, which is a similar service that we don't use anymore once they started charging.

Added the connexion bar. Whenever you're logged in with GCX, the connexion bar will appear on the top.
