Nunuhara Cabbage b3a660f8ec strings: copy-on-write
Only copy strings when they are mutated. This avoids copying strings in
cases where neither the copy nor the original would be modified during
the lifetime of the copy, e.g. when passing strings by-value.

This is purely an optimization.

Implement all of the string instructions that I could get the compiler
to generate code for. Still ASCII-only.

Nunuhara Cabbage 84df756faf Initial commit
An assortment of instructions have been implemented so far, mostly basic
stuff such as stack management. The following program can be executed:

int main(void)
{
    hello(2);
    for (;;) {
        system.Peek();
        system.Sleep(1);
    }
    return 0;
}

void hello(int n)
{
    int i;
    for (i = 0; i < n; i++) {
        system.Output("Hello, world! " + string(i));
    }
}
