Bug 13464 - Standardize the pagination class

 Bug 13464 - Standardize the pagination class

There are a few template which use a different wrapper class for the
pagination links. These should be made consistent for a consistent
style.

To test, apply the patch and go to Administration -> Budgets.

- On this page the pagination markup has been removed in favor of
  DataTables pagination. The budget tables were already sorted using
  DataTables, so having server-side pagination on top of that doesn't
  make sense.

In Administration -> Class sources:

- This page had pagination markup which was unused.

In Authorities -> Authority search results:

- Perform an authority search which will return more than one page of
results. Confirm that the pagination links are correctly styled.

In Search -> Item search:

- Perform a search which will return more than one page of results.
Confirm that the pagination links are correctly styled.

Since the funds are all displayed (and nobody complained), it makes sense to
display all budgets.
