Improve Cache()

Add the ability to create new Cache() objects from the current one (in the same directory). Allow the storage of int() (via str()). Don't store the key in the feed (useless, and not keeping it might make this service a little more less privacy-infrighting).
Add 'theforce' option to redownload xml

Useful for debugging
Add ability to redirect feeds

Useful for websites with API (facebook). Will be in use later.
Use more obvious varname for cache path
