Patch from Stephen Henderson: This patch primarily adds refresh, forward and back buttons to the search window. When a search is initiated this patch will check to see if that search type supports page traversal (currently not fully supported on Laconi.ca). If page traversal is supported then forward and back buttons will be made visible. When a user clicks a forward or back button a new search is initiated, this time incrementing or decrementing the page number. If the user isn't on the first page then auto-updates will be disabled until they navigate back to page 1, press the refresh button (or F5) or initiate a new search.

The refresh button performs the same action as pressing F5. The only change is that if refresh or F5 are pressed the page will automatically be set to page 1 in order to
access the newest results.
