fixed setting WorldGuard flag so greeting and farewell flags can be cleared by setting them to an empty string.
added config setting: buyland.allowedWorldGuardFlags and rentland.allowedWorldGuardFlags
these contain entries below for each allowed flag that can be set and its price.
Ex:
[buy/rent]land:
allowedWorldGuardFlags:
default: 0.0 This line does not matter, but should be there
entry: 150.0
game-mode: 300.0
Ticket 69 & 41: Added sign control to allow the adding of worldGuard region flags.
Sneak left-click on a Sell Back sign or Rent Extend sign to view available flags as defined in the allowedWorldGuardFlags section.
Added config setting: general.sign.showBuyLand [true/false] that will allow you to choose if [BuyLand] is shown on the first line.
if it is not shown, then "For Rent" signs will also show the rent price.
added /abl signFix command to update existing signs after this config setting is changed.
Ticket 71: When a sign for a rented region is right-clicked, the time remaining will be displayed.
Ticket 72: allow for a way for the owner, member or admin of a region to restore or move its sign.
