Adds a new filter to the page /token/given/ to specify the type of token awarded.

Closes T15988

Visited /token/ to see it works as before.

Specified a token type in the search menu, and checked that the results only include that token type.

Activate DarkConsole and inspect the Services tab to check the query with "burminate" has sense, and you see this:

SELECT * FROM `token_given`   WHERE (tokenPHID IN ('PHID-TOKN-misc-4'))   ORDER BY `id` DESC LIMIT 101

Removed the token type in the search menu, the results still include everything, like before.
