* Implements 'Set Home to Here'

* Implements 'Teleport Home'
* User Server has to be updated for it to save your home in grid mode
* home position accuracy is in int because the grid comms ExpectUser method tries to convert to Uint and crashes if it gets a float.  Added a convert to decimal in ExpectUser but to avoid a breaking change with old revisions, kept the save value in int for now.   Eventually it needs to be a float, but lets release another incremental version before doing that.
