Delete grid in crosshairs.

[mikeloeven]

just a concept for a easy delete command though i am not sure if the server API supports this
but for example if type /deletemode 1 left clicking while pointing at a grid in game will return the grids ID and automatically delete it.

this is useful for debris that have no name and cannot be safely located in the object browser due to proximity to more important unnamed grids.
typing /deletemode 0 disables this behavior and returns the cursor to normal.
