Reset Custom BPM

[Yathosho]

would be cool if one could reset a custom bpm to original at any point. also speeding up would be welcome, like 2x or 4x or any other multiplicator

even better:
support for custom code like what was done with Movement

i looked at the avs source and i guess it's super easy to implement - if i can manage getting the whole thing compiled

I'd also like to be able to define how a beat is detected, but I guess that that's another story.
