Fixed Team Healing and Buf bugs

Before, same team members could not send healing effects or bufs to each other. Now the code checks the team value and the bit sign value that denotes whether the effect does healing or damage (or is a buf or debuf) and determines if the effect goes through. So, bufs from opposing team members won't go through, and debufs from team members won't have any effect (no friendly fire, essentially).
Fixed a small bug in the Clear carrier, all debuf Status conditions are removed rather than buf status conditions.
