Title: Improve exceptions organization

I created a root `gittip.exceptions` module for exceptions to live at, and moved in those from the participant model.

Two benefits:
0. better organization
0. one step towards resolving circular import issues (eg `gittip/elsewhere/__init__.py` -> participant)

Tests all pass.
