Allow //pragma inline or /*pragma inline*/ for inlining a function

They are transformed by the scanner to the identifier `inline`, which is how the parser identifies it. This solves the comment problem, but it results in a funny side effect. Now, in inline mode, /*pragma inline*/ will always be the identifier `inline`, therefore this is valid:

    integer /*pragma inline*/ = 5;
    llOwnerSay((string)inline); // will say 5

Not overly elegant, but better than making up a specific token or declaring comments as tokens or the like.
