Bug 30840: Add support for barcode filters to course reserves

This bug adds support for barcode filters on the inputs in the course reserves module.

To test:
1 - Set itemBarcodeInputFilter to 'Remove spaces from'
2 - Find a barcode in your system and add spaces between each characters
    e.g. 3 9 9 9 9 0 0 0 0 0 0 8 1 8
3 - Past that barcode into the checkin box, success
4 - Browse to course reserves, ensure you have a course or create on
5 - Test adding a reserve, batch adding a reserve, and batch removing reserves
6 - The pasted barcode does not in any
7 - Apply patch and restart
8 - Pasted barcode with spaces can now successfuly be added, batch added, and batch removed from courses
