[Request] Map register

[BogusCurry]

Hello ;D
The most difficult for a user in a grid are the cordinates, so was nice when the webui has a cordinates register. I think is a good way to take the cordinates from the raster.

Here a example from the metropolis grid ;D

Looks like a good thing to implement indeed, the only problem is that reservation for a region isn't being handled by WhiteCore at this moment.

@greythane Is this something that we need to implement on Grid Server level still ?

This can easly be added by adding start and stop position then fetching the used coordinates from the DB since it is always /265 /265
