No longer writes everytime a value is added, since it could cause some issues if two instances of the script were run at the same time. Now it only writes when the Cache object is no longer in use (ie. garbage colllected).
Makes the whole "xpath rules" things useless. Almost any feed is now supported. CSS liferea stylesheets are also uneeded now, since readability cleans up html code a more efficient way. README was updated.
Now uses OOP where it fits. Atom feeds are supported, but no real tests were made. Unix globbing is now possible for urls. Caching is done a cleaner way. Feedburner links are also replaced. HTML is cleaned a more efficient way. Code is now much cleaner, using lxml.objectify and a small wrapper to access Atom feeds as if they were RSS feeds (and much faster than feedparser). README has been updated.
