Title: Explicitly require userscripts to end with .user.js

This prevents the situation where usercript a.user.js is edited, creating
backup a.user.js~, and each userscript is run, most likely with unintended
results.

Feel free to reject this one, I simply found it useful when I wanted to keep versioned userscripts for testing.
