Added sound object and more work on game_events.js

There is now a pause screen although it's quite buggy. Still need to
implement sound object into game. Also, need some music and sound
effects to test it.

Added level Select Screen and menu input handler

The input handler helps deal with insuring that pressing a button (like
up or enter) will only count as one press. Seems to be buggy on hitting
escape which is why the pause menu doesn't work right now. If somebody
could find or make an actual background image for the level select
screen, that would be great.
Added finished level screen

Levels can now be finished and will go to the finished level screen.
It's not finished yet, however, since it doesn't go to title screen yet
and I need to pass it fossils to display
Added cyanobacteria sprite and image
