Code review comment for lp:~cmiller/desktopcouch/couchdb-polutes-its-ini

The couchdb INI file may be updatec by couchdb to have a hashed password value, so we can not blindly take that to update the bookmark file any more. Now, store the username and password (yes in the INI also, but) in the bookmark file using a parsable format. Now, we can poke the value in initially, and later read the bookmark file to update the bookmark file.
