A week's worth of updates

Heartlight is almost complete! :) I've been programming this week to add the last missing game elements such as transport blocks and I've added viewport scrolling so the entire level can be explored. I'm now able to play individual levels of the game :D. Loading levels from the SD card is still missing...
On that topic... I haven't found a good replacement for the SD library (yet). The ones I tried didn't work or didn't give any real improvement on code size. So for now I'm sticking with the standard Arduino SD library and optimizing my code to fit everything in memory.
On the hardware side I've added a 1uF capacitor between D7 and the speaker. This prevents the screen flashes that would occur when a sound was being played.
I'm not sure whether I will keep the analog stick. It's not very useful and if I replace it with tactile buttons it will make the unit less bulky.
