Tables - add option for search functionality

[jwildfire]

Just a note that there is already a table.config.searchable option in the code, but it is ignored unless config.data_tables is true

Test Notes:

• Table should filter when typing in to the search box
• A note should be shown in the table for a search with no results
• search results should only contain data for the selected filters
• change a filter should reset the search results
• Pagination should update with the search
  • any search should take the user to page 1 of the results (regardless of the page the user was on when the search was initialized)
  • if there is more than 1 page of results, pagination controls should be shown
  • if there is only 1 page, pagination controls should be hidden
  • if there are no results pagination controls should be hidden
• should be able to search for numbers or characters.
