csdm_itemmode.sma:
* added three new config params for csdm.cfg: 'max_hnades', 'max_fnades', 'max_snades'; now you can set maximum number of grenades a player can hold
* since now hidden items are made a non-solid also; this prevents calling of Touch function when item is invisible
* hook_touch() function optimized a little bit: elevators & walls are ignored
csdm_misc.sma:
* BUY message is blocked if buying a weapon is blocked
* money balance is printed at HUD as 0 if buying a weapon is blocked
csdm_ffa.sma
* if FFA mode is active "Fire in the hole!" message & radio are blocked
TODO:
* menu issue
* overall optimization
* make a revision of dropped pack contents
