properly time based
made wavegen time based
Color blind mode

This is a very basic implementation of a color blind system, I added a
simple button under play (that doesn't fade)
Merge branch 'colorblind' of https://github.com/IceManQ/hextris into IceManQ-colorblind
Merge branch 'IceManQ-colorblind' into dev
restart only shows on pause
Merge branch 'dev' into gh-pages
made game time based, made game faster
setInterval for physics
Merge branch 'gh-pages' of http://github.com/hextris/hextris into dev
Merge branch 'dev' of http://github.com/hextris/hextris into dev
no colorblind button
made game easier + made gradient more smooth
prepping for prod
