One tax line- License/Installation - addToMaster 1 order

-Item description when showing needed dependencies instead of itemId

-Tax lines merge into one when apply to invoice

-Licenses and installation fees work differently.
   *"One timer" && quantityToInvoice==1 -> Installation fee
   *"One timer" && quantityToInvoice==0 -> License
   -Added a condition in updateOrInsertItemUsers() from orderDAS 
   
-BigDecimal.divide(q,2,RoundingMode.HALF_UP) in editOrders() from
webServicesSession

-addToMaster creates just one order, and updates master order with non
one timers.
	-editOrders(): if(!isOneTimer(newOrderLine)){add or update to master}
	-beforeSave(): delete moveOneTimers when addToMaster==1
