Allow "timerFireCountModulo" to be changed

[jyounus]

Hey,

It would be great if you would expose and make the var timerFireCountModulo: Int into a property which we can change. Currently it's a get-only property.

I'd like to remove the "the longer you hold, the faster it'll change the value" functionality and just make it increment based on my custom value (which in this case would be 2. From your comments: // 0.05 sec * 2 = 0.1 sec). That would be the ideal speed for me.

Thanks
