Initial UAC bypass documentation

This is the initial UAC bypass documentation. I have not yet checked if it works in the wiki itself, but if someone would like to go ahead and make the changes necessary to modify it to do so, feel free to go ahead.There may be some things that could do with further clarification as well. If you find anything, feel free to leave a note and edit it in the meantime. This is just meant to be a content writeup that can be used as a draft for expanding etc.
