GUI for launching grids. Early version, but should work fine.
Will execute all OpenSim services redirect their input/output/errors to the selected "GUI module".
This version has following "GUI modules":
* Windows Forms
* Windows Service (doesn't work yet)
* Console
* TCP daemon
This means that OpenSim can now run in a single console for those who want that.
Console functionallity is not too rich yet, but code/framework is there... more to come. :)
