Subject: #1065 Add windows mode

Add agent mode for windows platform.

Subprocess module for shell/run is cross-platform an no change was
needed. The subprocess will run with the same privilege as its parent,
ogclient.

TODO: Provide a windows installer. As of now,  an administrator
needs to install python and required libraries for this mode to be
usable.
