Add QQ macros for escaped config implementation

[jameslkingsley]

When merged this pull request will:

• Add the following macros:
  • QQGVAR
  • QQEGVAR
  • QQGVARMAIN
  • QQFUNC
  • QQFUNCMAIN
  • QQFUNC_INNER
  • QQEFUNC

This is useful for when you need to escape these macros in a config.

Before:

expression = QUOTE(\
    GVAR(camSlowDownInBuildings) = _this;\
    [ARR_2(QUOTE(QGVAR(camSlowDownInBuildings)), _this)] call CFUNC(saveSetting);\
);

After:

expression = QUOTE(\
    GVAR(camSlowDownInBuildings) = _this;\
    [ARR_2(QQGVAR(camSlowDownInBuildings), _this)] call CFUNC(saveSetting);\
);

While I do support this, you could've also used:

expression = QUOTE(\
    GVAR(camSlowDownInBuildings) = _this;\
    [ARR_2('GVAR(camSlowDownInBuildings)',_this)] call CFUNC(saveSetting);\
);

@commy2, do macros work inside single quotes??

[commy2]

Yes. See: https://github.com/CBATeam/CBA_A3/pull/317/files#diff-dc5764ac6d31dc8aa39a8b74be90f46fR22

I'm confused. Why don't we always just do this then?

expression = 'GVAR(camSlowDownInBuildings) = _this;\
    [ARR_2(QGVAR(camSlowDownInBuildings),_this)] call CFUNC(saveSetting);\
);'

I must have got it mixed up. I though that only works in SQF files.

Won't work. I think this is because ' is the escaping quote mark and not ".
