Bug 18035: Front-end changes to serials -> numbering patterns

This patch:
1) Uses datatables functionality on numbering patterns table
2) Shows breadcrumbs when using the form to add or modify numbering
patterns
3) Updates the Save, Reset, and Test Pattern buttons in the form to be
bootstrap 3 buttons

To test:
1) Confirm that datatable sorting works on all columns EXCEPT Actions
column
2) Click 'New numbering pattern'
3) Confirm breadcrumbs reads 'New numbering pattern'
4) Go back to numbering patterns and Edit an existing one
5) Confirm breadcrumbs reads 'Modifying number pattern '<name of
numbering pattern>'
6) Confirm Save, Reset and Test pattern buttons now show as bootstrap3
buttons
7) Confirm all buttons work as expected
