Suggestion PR to utilize LibCombatLogging-1.0 for combat logging.

[Vladinator]

The goal behind LibCombatLogging-1.0 is to try alleviate issues where multiple addons with various configurations will start/stop combat logging.

Sometimes one addon is setup to primarily log let's say raiding, but another might want to log keystones or Torghast or some other content, what often happens is when one addon loads in where it wants to log, it turns on logging, meanwhile the other addon might use the moment to turn it off since that addon isn't supposed to be logging here anyway, and this causes logging start/stop issues for the user.

The suggested solution is a library where the community can start/stop logging, but the library will properly turn it off once every other addon that started logging has stopped logging, this way we ensure we don't lose any combat data.
