Bug Fixes and Minor Adjustments

• Fixed a display issue in the warehouse stock tab for items that had no stock in any warehouse.
• Setting an item as nonstock will now remove all other inventory quantities (On order, Committed, etc).
• The tax table out of date warning will only show for users that have access to the create paycheck or view paycheck form.
• Fixed an issue that caused customer ID generation to fail when going from xxxxxx099 to xxxxxx100.
