block teleport to essentials homes of other players when other player is inside his faction border

[donvdp]

As i am sure many servers use essentials in combination with FactionsUUID. We have a player rank that allows the player to teleport to another player's home. so when an enemy player teleports to another enemies home its very easy to find the enemies faction home.

I would like to suggest a feature that would deny the use of teleporting to another players's home when the target player is within his own factions territory. But allow the teleporting to a target player when he is outside his faction territory.

for example 1:

• Player "A" has essentials permission to teleport to an other player home
• Player "B" is an enemy and is building within his faction borders Now player A is NOT able to teleport to player B's homes

for example 2:

• Player "A" has essentials permission to teleport to an other player home
• Player "B" is an enemy and gathering resources outside his faction borders Now player A is able to teleport to player B's homes

I know the argument can easylie be made to just disable the teleport to homes feature, but i dont want to do that if i dont have to.
