Feature request

Feature description

• Add permission for set especific warps.

• If the player does not have the essentials.setwarp or essentials.setwarp.* permission and only have the essentials.setwarp.[warpname] permission he can only set the warp with name [warpname]

• The same goes for deleting a warp.

• The system would be similar to the warps overlay system essentials.warp.overwrite.* or essentials.warp.overwrite.[warpname]

How the feature is useful

• The server admin can give a player permission to set a warp, for example: essentials.setwarp.PlayerName then the player can set a warp with his name and announce to his friends.
