Subject: ogclient-systray: add new systray program for ogclient

Add make.bat for an easier building process in Windows. This
script generates ogclient.exe and ogclient-systray binaries in
a ./dist directory.

Add ogclient-systray program. This python program polls the
existence of the ogclient process and shows a systray if the
ogclient service is active.

Update utils/create_version_file.py to generate information for
the systray binary.
