This patch fixes some problems with Bazaar adapter, namely:

• Renames shown correctly (past behaviour was: show as modified);
• History doesn't stop on first entry rename (uses internal object ids to retrieve changes);
• Last revision the entry was changed in displayed correctly (past behaviour was: sort alphabetically, i.e. if object was changed in 2, 9, 13, then 9 would be shown);
• Field tags changed a little to make it clear to user that he can either enter local path to branch repo or http:// URL).
• Bazaar adapter uses change.revision to store internal object ids which are pretty long, not revision number. So when viewing repository/revisions/:id, these long ids are shown after diff link, not before it (more convenient for bazaar, doesn't change anything for other SCMs).
