Autogroup hotkeys

• ‎Alt + number‎: Makes permanent autogroup out of currently selected unit types. New units then join that group when they first become idle.
• ‎Alt + ~‎: Removes currently selected unit types from the autogroup.
• ‎Ctrl + ~‎: Selects one unit out of currently selected units (closest to your mouse cursor) and removes it from any groups (not removing type from autogroup, just current unit from group).
