New Feature: Expenses added to the Dispatch

You can now add expenses directly to a dispatch when you create or edit a dispatch and it will be deducted from the Load Profit.  When you view these expenses under the Expense link in the black navigation bar, they will have the dispatch number attached to it.  If you ever delete a dispatch that had expenses attached to it, the expenses will stay in the expense area, but not be attached to any dispatch.  You can still add expenses directly to the Expenses in the navigation bar, they just won't be attached to any dispatch number.
