Beta Mutation 2.0 file

Removed useless tutorial text in the .txt file and cleaned up the population.txt file for minimal file size.

Re-enabled the survivor collision

Made a new sub-mutation that disables the survivor collision for those that don't like it

Further implemented Left 4 Dead 1 cvars (such as ragdoll limit, splitscreen cvars and friendly fire factor)

Removed unused cvars

Removed a cvar that potentially caused the infinite loading glitch

Special infected can now push commons thanks to survivor collision

Removed bot friendly fire

The mutation no longer changes crosshair color to green for user convenience

Updated the addoninfo.txt file to include the correct author alias and improved the description.
