Bug 34257: Limit item types by branch in batchMod.pl

Bug 34257: Limit item types by branch in batchMod.pl

To test:
1. Go to Item types administration.
2. Set some items types to be limited to a branch you are not logged in as.
3. Find some items from the branch you are logged in at and go to Batch item modification.
4. Add the barcodes and attempt to edit the item type to the one you limited in step 2.
5. You can change these item types to ones that your branch should not be able to.
6. Apply patch
7. Try steps 4 -5 again but this time you should not see item types in the dropdown that are limited to other branches.
