Fixed typos: tinytouchlib -> TinyTouchLib

Hiya,

Long time user (of ws2812 libs), first time pull requester.

Playing around with libs, didn't compile, and the fix was just uppercasing filenames. Thought you'd want to know.

And a random Q: have you tried this technique with multiple buttons, for instance on a Mega part with more pins? The sensing loop might get really slow, huh? Just wondering before I sink an hour so so into it. :)

It's traditional in C to use lower case filenames though, with underscores if needed. Never CamelCase.
