Started work on bzr4idea v2

Written for bzr4idea by Patrik Beno on 2008-11-12

Work has begun on version 2 of bzr4idea.
We are trying to utilize svn4idea code base for this purpose, hoping for faster progress towards full Bazaar integration. Also, this is a part of the transition to IDEA8.
Hopefully, within November 2008 we'll have something usable...
