[CoD2] create functions in .menu-files!

[IzNoGoD]

Basically created a simple && for menus (logical AND, in case if(a && b) set c 100)
code:

		                execnow "set first_ok 0";
                execnow "set second_ok 0";
                execnowondvarintvalue first_check 100 "set first_ok 1";
                execnowondvarintvalue second_check 200 "setfromdvar second_ok first_ok";
                execnowondvarintvalue second_ok 1 "set result 10";
                execnowondvarintvalue second_ok 0 "set result -10"; 
	

which basically does this:

		first_ok = false;
second_ok = false;
if(first_check == 100)
        first_ok = true;
if(second_check == 200)
        second_ok = first_ok;
if(second_ok)
        result = 10;
else
        result = -10; 
	

It is however not very possible that you can use this for a double &&, as the amount of execnow's and execnowondvarint's is limited per action. You'll need a second menu then.
