Reorganize settings directory, custom purple paths

The settings file-hierarchy has been changed a bit:
	* Cardie/
		* preferences
		* Accounts/
		* Cache/
			* Accounts/
			* Add-Ons/

`Cardie/Protocols` is now `Cardie/Accounts`, and the cache directory
has been split into two. `Cache/Accounts/` is for account-specific
cached data (e.g., cached roster icons, data, etc.), and
`Cache/Protocols` is for protocol-wide settings/data.

For purple, this will be used as the user's libpurple directory,
which has been moved from the default of `~/.purple` (yikes!)

Some plugin search-paths have been given to purple, too― lib
directories + "/purple2/", and Cardie/Cache/Add-Ons/purple/plugins/.
