This commit is replacing non-named usages in reviewboard/avatars to use
named logging instead. The purpose of this change is to automatically include
more information about the module where the logging message came from so that
the messages can be of more use when diagnosing problems from logs.

Ran ./tests/runtests.py reviewboard.avatars.tests and passed all 21 tests.
Checked previous reviews for consistency.
