Generate results for all rows in table

update_results_db.php now looks at every row in the search table and
generates a search URL. It creates a php array of these URLs and dumps
the parsed results in the results table.

Next steps:
- Using multiple search tables into multiple results tables
- Sanitizing SQL results
- Determining number of page results and return results for that many
pages
- Remove low quality results
- Log searches that don't produce many results
