windows-password and start/stop/terminate support
*THIS CODE IS GETTING OUT OF CONTROL*
You can now get a windows instance's administrator password by
passing it the instance id, the proper key file and the windows
password flag:
python awsbuilder.py -i "i-46afd13d" -k /Users/mg/mg-repro.pem --windows-password

Append the flag on a build and it will print it out for every instance.

--start --stop and --terminate work pretty much the same way, except
there is also group support. Didn't put group support for winPass in yet

Also, code base is a freaking mess. Need to refactor soon and turn the
spaghetti maker off!
