Updated the code work again with the updated Space Engineers

* Added support for different grids
* Added support for block command, you don't need a group anymore.

Send the command <action>#<groupname> or <action>#<blockname> via antenna to send to all grids.

You can also target a specfic grid with <action>#<groupname/blockname>#grid
The grid name is determined by the setings.

You can add a line "grid=<gridname>" without qoutes to the custom data section of the Programmable block.
If the grid is only defined in custom data, or only in hte command, it won't work. you have to update all your sending script with the new <grid> name if you specify a grid in th settings.
