yotta windows install script

I created a branch for a windows install script i'm working on. 
Currently the script pulls down dependencies for windows only, it can differentiate between 32bit and 64bit. 
The script then runs the isntallers in order and prompts the user to click through them. 

In the future I would like to make these installers silent, but that requires some brute force hacking on the exe's and registry editing. If there is demand can work on this later.
