Made a lot of changes to the benchmark site.
Deleted compiled files.
Fully working AES benchmarks.
Many small changes RE: Workers

 - Allowed passing of options to workers.
 - Changed AES128 workers to allow variable sized keys. (Now just AES)
 - Made fonts smaller so its a tiny bit easier to see multiple
   benchmarks.
 - Workers are now opened and closed upon each test to "clear memory".
   This is related more towards the asm.js tests.
