This commit contains a bunch of work that comes from Meatballs1 and
Lesage, and updates the bypassuac_inject module so that it works on
Windows 8.x and Windows 2012. Almost zero of the code in this module
can be attributed to me. Most of it comes from Ben's work.
I did do some code tidying, adjustment of style, etc. but other than
that it's all down to other people.
