Combine source_created and source_changed
...
As discussed in #214 , source_created and source_changed didn't really
have clear definitions. In truth, their names and separation betray
their origins as model receivers in earlier versions. The "source group"
abstraction helped us get away from thinking about things exclusively in
terms of models, but these remained as an artifact.

Reduce calls to backend
...
Reading from an `ImageCacheFile`, will result in accessing its `file`
attribute repeatedly which would result in the `before_access` signal
being dispatched, which in turn would result in many unnecessary calls
to the image cache backend. With this change, we don't send
`before_access` if the file has already been created.
Similarly, we don't need to try to generate the image if we know for
certain that it's already been generated (because we have a reference
to it).

Store cachefile strategy on file; not generator

The file can appeal to the generator for the value, but it shouldn't
require it; it just does that as a convenience.

just a better description, even if different strategies can change the
behavior so it isn't really very cache-like.
