Drive script

Fixed valid_format checking to support Windows and OSX bundles too (issue #3). Single locales are also supported too (before it would only recognize things like en-US or es-ES).

Added specs done at the beginning of gsoc. Not updated to the current status of development, but still useful.

Changed ?dl=0 to ?dl=1 in the shared files to automatically force the download. Couldn't find how to specify it using the Dropbox API

Lots of changes: added blacklist and stats via sqlite database, cleaned the code (including comments), and minor changes on SMTP module. Both SMTP and XMPP tested. This is the code that will be submitted to melange.

Current supported commands.
