Added request creation and processing to role.py.
This is used if you want to request to become a certain role for a group. For instance becoming a club member.
The process request view will also be used to cancel outstanding invites might this be necessary.

# Until model subclassing is a possibility, a mixin class is used to add
# the necessary functions that may be contributed for geographic objects.
class GeoMixin:
"""
The Geographic Mixin class provides routines for geographic objects,
however, it is no longer necessary, since all of its previous functions
may now be accessed via the GeometryProxy. This mixin is only provided
for backwards-compatibility purposes, and will be eventually removed
(unless the need arises again).
