added:
- TpToFreeRegion command that allows to find a free region without using the gui
- ListRegions command that allows finding out the IDs of the regions a player already owns
- automatic regionselector that can select regions by using the players position instead of forcing the player to type in the regionID. (Currently works with: addmember, removemember, terminate, resetblocks, reset, unsell, info, buy, extend)

new permissions:
- arm.member.tptofreeregion
- arm.member.listregions

new commands:
- /arm listregions (player)
- /arm tptofreeregion [REGIONKIND]

fixed:
- Added static getHandlerList() method to API
- Nullpointerexception if someone tries to select a subregion that doesn't exist
- Now the autocompleter for the sign-linking-mode doesn't suggest not working commands anymore
- the default currency is $ now
