Allow suppression of certain types of warnings in certain code

[fredrikr]

It would be useful to allow both library authors and game authors to suppress certain warnings. Maybe something like:

#Suppress #warn_ununsed_local #warn_unused_array;
Array my_stuff -> 100;
[ MyRoutine x;
  rfalse;
];
#EndSuppress;

This is interesting, and it's fairly common idea in mainstream compilers. However, it would be a lot of work and would touch a lot of code.

The usual way to suppress array-type warnings (and bounds checking) is to copy the array address to a local variable. A constant also works:

Array arr -> 100;
Constant arrc = arr;

[ Main val;
	val = arrc-->5;
];

(It compiles to the same code.)
