Move document sidebar entries extraction to document.View
This way other modules can benefit from the same logic. Also make use
of the sidebar.getSidebarMenu method so that getMenusForScope is no
longer specific to full menu's.

# 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).
