forms: group name should not start with special character

The route /<group_name>/ is used for displaying the group infos. If you
want to support additional sites (like all public browsable groups),
you need a possibility to recognize such urls. So the group name now
has to start with a non special characters. So we could support paths
like /_all/ for special pages.
