Rework disguises into their own addon

[m0kka]

Having the disguises sorta awkwardly duct-taped into equipment isn't ideal, would like to move disguises to their own addon entirely for better overview and management.

Additional work items:

• [x] fnc_equipDisguise: move doIfSpotted and removeEvents into separate functions instead of putting them in global vars (...each time the function is called)
• [x] fnc_equipDisguise: fix error with removeEventHandler and CBA_fnc_removeEventHandler
• [x] Make the ACE_Interaction menu for equipping disguises dynamic instead of having to define a new interaction entry for each new type of disguise

@m0kka What error is being caused by removeEventHandler and CBA_fnc_removeEventHandler?

[m0kka]

The getVariable getters in lines 151, 154 default to "" if the variable was not set/deleted, which is not a valid value for either removeEventHandler or the CBA equivalent. default variable should be -1 (or the statement executions should be guarded with if branches against execution)

[m0kka]

don't know the specific circumstances of when this will error out (since the event ids should be correctly saved most of the time), but I did see it pop up in an rpt before
