Overhauled RSS and weather, added $curl.

Browse Source 
I've taken the curl stuff out of weather and RSS and moved it into it's
own entity.  It should be easier to create curl-based objects if needed
now.

Some objects may create threads, and sometimes these threads will
not be destroyed until Conky terminates. There is no way to
destroy or clean up threads while Conky is running. For example,
if you use an MPD variable, the MPD thread will keep running until
Conky dies. Some threaded objects will use one of the parameters
as a 'key', so that you only have 1 relevant thread running (for
example, the $curl, $rss and $weather objects launch one thread per
URI).
