Finally added a thumbnail image for the mutation(s)

Hell on Earth:
-Jockeys respawn slightly faster
-Raised the max specials cap to allow Tanks (hopefully)

Added a new mode to the Mutation, Hell on Earth. This mode was not balanced to be beaten on higher difficulties, but play if you so desire.

Gave a lot of changes

On Jockey Rush:
-Only 4 Jockeys will spawn at once, never more.
-Spawn time has been changed to be slot dependent rather than time dependent.

Monkey Mode:
-Only 8 Jockeys will spawn at once, never more.
-Tanks SHOULD spawn more consistently during finales.
-Spawn time has been changed to be slot dependent rather than time dependent, but here they should spawn slightly faster.
-You now start with 2 Pistols

This was done in the hopes to balance out the Mutation more fairly, especially for those wanting to play this on the higher difficulties. There might be a future edition to the Mutation that would be more crazier than Monkey Mode, designed to be unfair.
