Restore System should detect existing backups

More complex restore system in web interface (Automatically detect backups in multiple locations)

I made an interface that will detect existing backups and allow the user to revert to them. At the moment it is not fully functional. Here's how it works:

Everytime a backup runs, a record of the date and source (e.g. dropbox - maybe source is the wrong word) is saved into /home/users/memories.list which is a json list of all the backups the user has.

[
  { "date": "2012.09.10.00.00.00", "source": "Dropbox" },
  { "date": "2012.09.10.00.00.00", "source": "Dropbox" },
  { "date": "2012.09.10.00.00.00", "source": "Dropbox" },
  { "date": "2012.09.10.00.00.00", "source": "Dropbox" }
]

This list is read by the autobackup plugin and populates a table for the user. The user would then switch between the different backups while not losing their current changes.

I still need to:

• Make the backup process modify memories.list
• Make backup process check that stuff in memories.list is still current
• Make the plugin acquire and extract the needed backup
• Make the plugin switch data directories

Added a script that finds all available memories in 0074ec39 and its tested and working.
