* compress non-GIF media as JPEG
There are some problems with this approach
- Potentially re-encoding files
- Lots of code in the controller
* Compress GIF > 5MB into static JPEG.
This isn't ideal, but a stopgap to prevent people from sending huge
GIFs, while also giving them *some* kind of feedback (e.g. a static jpeg
is sent rather than their being no indication to sender+recipient that
anything was attempted.)
* spell bmp correctly
