cz750 fix for 1.16

All items (weapons and buttstocks) were edited to match the current vanilla state;
So buttstocks are not reducing bullet dispersion now but they are reducing both sway and recoil;
Adjusted HP and initial bullet speed for all weapons;
Disabled ability to repair weapons with duct tape (sry players!);
Buttstocks now can be repaired with epoxy putty;
Fix for sound of CZ 705, now it sound the same as Winchester 70.

Fixed:

• Hammer position of CZ 75 Duty
  
• Animation of magazines handling
  
• Position of VZ 58 in hands
  
• Minor textures and materials adjustments
  
• Few wrong paths from my another mod - Thx Ondra for reporting it
  
  Added:
  
• Green camo versions of CZ 805 A/B

Fixed the ability to attach improvised and AK/M4 at the same time

Fixed:
Null pointers caused by rail hiding script - thx to DaOne for it
CZ 750 script was updated to 1.08 state (old variant could be bugged sometimes)

Sa vz. 58 Special Forces variant
Two types of buttstocks for ^ with different characteristics
