Rework of F3 Gear component:

* moved relevant files to new folder f/assignGear/
* renamed files to be consistent with the f_ naming scheme. Maybe use fa_ for the faction files?
* clients now send their required gear to the server via BIS_fnc_MP: Will work with JIP.
* new function: f_fnc_assignGearS - server-side component of assignGear.
* Reworked uniform/cloth assignment:
Which unit gets which uniform is now defined in an array in the "COTHES AND UNIFORMS" subsection
* Added comments for clarification.

NOTE:
* Comitting this would require slight adjustements in the fixes made to JIP.
* This changes the assignGear function's name to f_fnc_assignGear (from f_fnc_folk_assignGear). Adjustements in the mission.sqm have been made.
* This includes the minor fixes from https://github.com/ferstaberinde/F3/pull/201
