Visual & audio enhancements

[flukeout]

Will keep track of some stuff here...

To See

• When a new leader takes over, "pop" the leader indicator
• ~~Add more variety to the screenshake, and apply it independently to the main elements~~
  • Right now they all receive the same shake
  • Solved by dynamically creating and inserting css animations per element that receives shake
• Fix the z-indexing of some of the particles
  • ~~The black covers over the blasts sometimes appear above the smoke~~
  • When you run into a wall, the glowing head snake bit has a higher z-index then the particles that shoot of it - look into that
• Add a cooler spawn indicator

To Hear

• Add a sound when a player spawns
• ~~When you drop a bomb, don't use the 'lose segment' sound, but add a unique sound~~
