Shefki:
	- Add throttling for repeating timers.
	When the client is busy the animation system will still call the
	OnFinished function the same number of times as though it had a delay.
	This is different behavior from AceTimer where if more time has elapsed
	than should have since the last fire only one fire will happen.
	- Add tconcat upvalue I missed putting in when I put safecall in.
	- Add .docmeta file.
	- Initial commit
