0cc7938400 Re-integrate receivers module
Somewhere along the line, a change got merged that stopped using the
receivers module. This re-integrates it and moves changes made to the
old receivers (static methods on ImageSpecField) to them.

c8733c4707 Change how signals are used
Signals are now connected without specifying the class and non-IK
models are filtered out in the receivers. This is necessary because of
a bug with how Django handles abstract models.

Closes #126
