Finally found the root problem of states not being saved across maps (when completing a chapter and resolved it.

All irrelevant modes will no longer save states and will reset upon every round start.

- Fixed Bill essentially being invincible.

- Possible fix for states not being saved correctly when the team has to restart the chapter.

- Fixed a bug where level transitions doesn't apply player's infection status.

- Fixed defibrillators not properly converting into adrenaline spawns.

- Adrenaline shots will now reset your health to 100 and set your revive counter to 0.

- Using a First Aid Kit (as a result of a fallen survivor dropping it) will grant 150 health to the subject of its healing and cure them of the infection.
