1) It moves the BeginDocument to a earlier place in the call change

2) Fixes the negitive page range display problem
3) Improves performance by reducing the delay on pages not in the page range, i.e. before if you printed the 30th page out of 31 you had to wait 15 secs to get to the 30th page to print it.
4) Added AbortDocument, so now when Print jobs are cancelled we call AbortDocument and remove them from the print spooler
5) Fixed a couple of minor issue with Canceling and cancelling mail printings
6) selection was not printing correctly. The problem with selection was that the clip was not being set corrctly.
