Move test utilities outside of the tests dir

It's less confusing -- this way it doesn't look like it is a module
testing the easy_thumbnails utils (and if utils tests get added, they
can go here instead).
Make a way to avoid generating missing thumbnails

With a Thumbnailer instance, thumbnailer.generate = False or explicitly
via thumbnailer.get_thumbnail(..., generate=False) returns None rather
than generating thumbnails that don't exist already.

A new easy_thumbnails.signals.thumbnail_missed signal allows you to
catch these misses and deal with them separately (e.g. offload
generation to a queue / separate process).
Add a thumbnailer_passive filter

Allows for templates to use the new passive get_thumbnail method for
aliases.

Adds tests for this tag and the thumbnailer filter, which was also
missing tests.
Document the thumbnailer filters

Minimal documentation, but it's better than nothing.
