To whom is this feature relevant?
-all

Please provide a one line description of the feature:
-Generic VGrid is a special case, that we should simplify where possible

How would the new feature work (appear in use)?
All users should automatically be members of Generic and have access to the
associated VGrid features including monitor, shared space, wiki and public
resources.

How would the new feature be implemented?
Wild card support in the shared/vgrid.py module checks should make it easy
to simply provide '*' as members and resources for Generic. This will
automatically allow everyone to participate in Generic.

Please provide any additional information below.
The wild card support will also help in issue #17 where we would otherwise
need to have vgrid owners guessing at future sandbox IDs to allow sandbox
contribution. With wild cards they can allow 'sandbox*' to allow all
members to contribute sandbox resources.
