Changes made at Gem to install gon, attachments were rewritten to haml
Refactored attachments screen to HAML.
It is not finished yet, I still have to figure out how to put the tags back in again.
Everything else is functional (including coffee scripts).
Missing file from last commit.
It is the view "edit" for an existing attachment.
Without this file, choosing the option to send a news attachment would fall in 404.
Included tags functionality again to attachments inside space.
The entire code need some refactoring to remove unused js functions.
Removed unused js functions, removed unused files and inserted TODO tag to remove js code from view
