+ fix bug in Python binding of Quarter viewer
split the revision information

to a number for those commits common with the blessed master and a number for
those ahead of the current master

choose the url from available remotes
remove ssh username
accept ssh://[...].sf.net as origin
list multiple branches in version info

in case last commit is a octopus merge
calculate the revision number from reference commit
call git branch with the --no-color option

in order to prevent escape codes from becomming part of the branch name
