Added Recent Changes page and version info in the footer.
Added filtering to the localization namespaces page, allowing users to find deleted namespaces.
When creating a phrase or namespace with a conflicting key, the user will now get directed to either edit the existing phrase or namespace, or change the key. If the existing phrase or namespace was deleted, they are given the option to restore it.
Fixed errant behaviour with usernames and email addresses containing underscores.
When deleting a localization namespace, all the associated phrases will now also be deleted. Likewise, when restoring a namespace, all phrases are restored along with it.
Projects marked as Changes Required or Under Review are now only accessible by moderators and managing members of the project. Previously, they could be still be accessed by other users by going directly to the URL.
