Suggested fix for issue #224, FlxTilemap.ray() Result value always null

[FlixelCommunityBot]

Issue #225 by: cr0ybot

Added rayHit() function to FlxTilemap that explicitly returns an FlxPoint if the ray hits anything, and returns null otherwise. Default ray() function relies on passing a variable as reference to receive the hit result, which does not seem to work. See http://stackoverflow.com/questions/3708371/actionscript-pass-by-reference

This is unnecessary, see: AdamAtomic#224 (comment)

A better fix would be to change:

if(Result == null)
    Result = new FlxPoint();
Result.x = rx;
Result.y = ry;
return false;

to

if(Result != null)
{
    Result.x = rx;
    Result.y = ry;
}
return false;

This makes the code clearer and removes an unnecessary new FlxPoint() creation.
