Ability to pay for commands (through economy) is now checked before firing events which can be canceled, and actual payment made after making sure the event isn't canceled.

Browse Source 
Added Econ.hasAtLeast(EconomyParticipator ep, double delta, String toDoThis) method to check if an account has at least a specified amount of money in it. Also added related FCommand.canAffordCommand(double cost, String toDoThis).
