//Seekbuttons.m:  My bitch.  This is *loosely* based on the concept of the autorepeating script by...?  Anyway,
//I say loosely based due to the fact that I didn't actually try to mock the code used in the afformentioned script,
//I just mention it because it's where the idea came from.  I wanted to have back and forward buttons that also
//had seek actions when held, and here's how I did it.  I'm not sure if this was ever corrected in the ARVB script, but 
//the seek speed actually accelerates the longer you hold it, and then slows again if it skips to the next song.
//All code by me, Digitalhigh.
//-----------------------------------------------------------
//How to use this for your own fun:
//(Sample XML)
//<groupdef id="whatever">
//	<button id="previous" action="" image="btn.prev".../>
//	<button id="next" action="" image="btn.next".../> 
//	<script id="seekbuttons" file="scripts/seekbuttons.maki"/>
//</groupdef>
//
//Now all you've got to do is compile this and go to town.
//-----------------------------------------------------------
