Subject: [PATCH] Fix/hack ErrorPageError to work from non-UI contexts

Right now, ErrorPageError *assumes* you're never running on the cli
or the API. It's kinda a crappy superclass to use for errors unless
you're 1000% sure you'll never hit that code path. Yay assumptions!

Ideally, all of this report() crap is cleaned up and unified across
the like 1192902117 places we have it spread out, but for now just
detect the scenario and delegate back to MWException, which does the
right thing
