Groups, Group Nano powers and Revive (#129)

* Initial Group Implementation

* Request/refuse/join and leave groups.
* Chat into groups.
* Get status updates on every group member each tick.
* Owner leaving the group destroys the entire group.

* Added more nano powers

* Revive for both variants work.
* Many nano powers now have a group variant working.
* Enemy checks for aggro before retreating.
* Enemies keep aggro on dead players with revive nanos out.

* Further Nano powers + Bugfixes

* Infection damage now relies on bitcondition flags.
* Antidote power now works.
* Improved how groups handle leaving players.
* Fixed mob aggro range.
* Group Healing is now functional.
* Possibly fixed the player being unselectable bug.
* Fixed indentations.

* Dismiss nano when starting a MSS ride

* Sneak, Invisibility and Bugfixes

* Sneak and invisibility affect mob aggro.
* Possibly bugfixed equips not showing to other players.
* Aggro checking is less likely to cause nullptr related crashes.

* Group PR cleanup.

* Made sure to label all hacky workarounds
* Implemented the Antidote nano power the right way
* Cleaned up the way various little things are written

Didn't have the opportunity to actually test groups.
