Add ability to accept/decline applications (simply updates status of application from "pending" -> "accepted"/"declined").  Also added error checking
Update group users list on accepting of application
Fix - do not add user to members of group if application is declined.  Also moved functionality to update instead of edit (restful)
Update method in view for edit->update change
Fix logic (sym-string comparison)
Add ability for leaders to destroy groups (their groups) and for members to leave groups
Hide apply button from users who have already submitted an application. Added groups (back) button
Add styling so apply buttons are inline as opposed to one per line
Disable apply button if the current user already has a pending application
Rearrange logic - maybe a bit clearer
Merge pull request #11 from Druotic/group_join_leave
