- board-search.php Now properly calculates tag weight.

- boards.php Passes $search parameters into Twig.
- js/board-reictory.js Stores last search parameters and handles tag click events.
- Twig now passes old search parameters into the search form.
- Tags now link in such a way that they will preserve form data and other tags when clicked in a browser without JavaScript.
