Allow user info to be retrieved without groups

Some parts of dokuwiki (e.g. recent changes, old revisions) can
requests lots of user info (to provide editor names) without
requiring any group information.

This change also implements caching of user info by authmysql &
authpgsql plugins to avoid repeated querying of the DB to retrieve
the same user information.
