in_group template filter
Allows you to search if a user belongs to a given group. Along the same lines as snippet [390](http://www.djangosnippets.org/snippets/390/), but uses a regular ``if`` tag so it is more flexible. (Updated for efficiency. Running a boolean test on a QuerySet avoids a bit of unnecessary overhead.) (Updated to accept a list of groups.)
