Version 0.8.8
  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:
      buyland:
        allowedWorldGuardFlags:
          entry: 150.0
          game-mode: 300.0
  Major reworking of sign clicking actions were done to accomplish the following 4 ticket entries
  Ticket 69 & 41: Added sign control to allow the adding of worldguard region flags
    Sneak left-click on a sell back sign or a rent extend sign to view available flags as defined in the allowedWorldGuardFlags section.
    Added config setting: general.sign.showBuyLand: true/false
      This will allow you to choose if [BuyLand] is on the first line of the sign.
      If it is not shown, then "For Rent signs will also show the rent price for the time frame indicated.
      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.
    Reworked creation of all BuyLand signs to make this very easy.
    Create a new sign with the following lines:
      [BuyLand]
      regionName  (the name of the region)

  Ticket 44: Addressed multi-part request
    Show price with click on sign. (see above)
    Show time left with click. (see above)
    Have option to hide the [BuyLand] from the sign and utilize the extra line.  (see ticket 69 and 41 above)
  Ticket 75: Add permission buyland.offlinelimit.exempt to prevent the automatic selling of a region for a player that has not logged on for a set number of days.
