Per-team island homes

[TheWranger]

Is your feature request related to a problem? Please describe.
Currently, each player can have their own island home (teleport point); the problem with this is that it stops islands from having a singular teleport point where all of the team members can teleport to (like in Factions/Towny/Other plugins). This also takes the "team" idea of out island homes and instead makes it a "per player" thing, which some servers might see as going against the idea of island teams.

This would also mean that teams would have to design their island in a way that makes it so that different structures (mob farms) are quickly accessible from the home(s)

Describe the solution you'd like
A configuration option that makes it so that players do not have their own homes that they can set and instead makes it so that each island team has the same homes. This should also come with the following changes:

• The island owner's island home permissions dictate how many homes the team can have (if owner has permission for 2 homes, the team can have up to 2 island homes)
• '/is sethome' should be added to the Command Ranks menu

Additional Context
Server owners might prefer the current way things are handled so that is why I think that this function should be toggleable.

This would mean that island homes would be stored per-island instead of per-player.
