Rev 441 changes:

Added:
* Now size and position of stargate vgui menu will be saved after gmod close.
* Client-side console command "stargate_reset_menu", it restores position and size of stargate vgui menu to default settings.

Updated:
* Recoded stargate vgui menus, now finally have optimized code and only two menus (not ~20 separate menus for each type like before).
* Now orlin stargate and nox hands havn't fast/slwo checkbox (because have no effect).
* Better synchronization between menus - all data (dialled addresses etc) now shared for all gates (before this all menus have own data).
* Some other slight optimizations for menus.
* Now shield from stools by default can have size up to 2048.
* Now shield from stools at 50% stronger.
