Bug 36032: Use a single angle in the "Next" button

Bug 36032: Use a single angle in the "Next" button

The "Next" pagination button in the OPAC result list has a double angle
whereas the "Previous" button only has a single angle. This patch fixes
that error.

To test:
1) Do a search in the OPAC with more than one page of results.
2) Observe that the "Next" button has a double angle whereas the
   "Previous" button has only a single angle.
3) Apply the patch.
4) Repeat steps 1 and 2.
5) Verify that the "Next" button now has a single angle.
