Mobile support for controlling bird

[matcool]

Uses touches from p5 to check if user has touched screen
probably not that useful

[meiamsome]

I would prefer this change (Parallax, using a speed variable) to be separated from the touch controls PR, please. Also you misspelt speed in your variable declaration.

[matcool]

Oops i meant to change those in another branch then make it a separate pull request

[meiamsome]

I'll leave @shiffman to chose whether to merge

[shiffman]

I like having this here! I wonder -- is there a simpler way to implement just using the p5 touch events and not worrying about multi-touch?

[DaGuT]

@shiffman there is....
@MatCorgi please, change all your code to just new function in sketch.js
:D

Just add. Not gonna commit myself, as it will not be approved anyway :D

function touchStarted() {
   bird.up();
}

I have tried that before and for some reason the bird jumps twice when touching quickly.

Seems to be an issue with p5 and chrome 56:
processing/p5.js#1811

I'm 50% (xD) sure that it will work properly on mobile (not in chrome dev mode)

[matcool]

Just tested it again and still the same thing, press once quickly and the bird jumps twice (when touch starts and ends)

Awesome! Thank you!
