Move HUPEvents under the Hupper namespace
Rename Transform to Hupper.Transform
v2 manifest.json

Change the behavior of the background and options pages:
Move inline JS into external file from options.html
Remove background.html and replace with background.js
And some undocumented stuff. I forgot to commit when I needed, so now I
just rewrote, moved some and some other stuff. Anyway, these codes are
several years old, did anyone like his own code which was older than a
week?
Move HUP under the Hupper namespace
Use named function
