Log Message:
-----------
Catch some remaining MD5 gunk

- One attempt to require a missing JS file (breaks journal pages due to 404)
- Stop requiring MD5 library in places that don't use it
- Guarantee MD5 library is available for the two places that actually still call
the `MD5()` function (xpost.js and jquery.crosspost.js)
