Fix !sandbox clean breaking factions when removing founder (#147)

* Added !tphere command to teleport players to you more easy

* Added command to Kill given player instantly

* Added Eject Command for specific player

* Added Ejectall command for grids. You can also use it by looking at the grid in question

* Typo fixed

* Turns out essentials already had eject and kill. Moved my code over and improved it a little to deal with offline players as well.

* Code-Review reworks

* Uses VisualScriptLogicProvider to kick members

Main Advantage over faction.KickMember is that KickMember is only used for actually kicking members.

If the founder is kicked the next player in line wont be promoted. There are isntances where the identityID of the founder was still in the safe file, but the identity itself was deleted. causing internal NREs on faction.Members.Keys as the founder ID will always be in the members list.

But without identity building the DictionaryReader fails internally as it doesnt like NULL
