Changed the SRID config storage
Temporary remove the plot-animal relationship
Added SRID to geom column definitions
Remove the pyramid debug toolbar

It's really annoying with multiple json requests,
really prone to errors.
Small refactoring
Added CUD methods for plots.
Added URLs for plot CUD operations

They work with GET parameters, as well as the
info about the logged user.
First version of the map plot CUD tools.

Cannot do multiple delete and update operations
as of now due to a session problem, but single
operations work perfectly.
