Toggle between two modes

[ekinhbayar]

@danschenker and I had this neat idea that I'll try to describe below.

Add a toggle that switches between the 'serene' vs 'rock' modes.

Current notes that are played for each event will be the 'serene mode' sounds and for the 'rock' mode we will need new sounds, perhaps some nice and short riffs? same notes but from a distorted electro guitar? Any cool sound that would do :-)

The toggle should also change the logo from the current one (for serene mode) to the neon logo

@ekinhbayar if all you need are the samples, I've got a few friends who may be able to record some. I'd assume they should preferably be in a similar scale to compliment the "serene" mode, right?
