Refactor filter in LinkDB

  * search type now carried by LinkDB in order to factorize code between different search sources.
  * LinkDB->filter split in 3 method: filterSearch, filterHash, filterDay (we know what type of filter is needed).
  * filterHash now throw a LinkNotFoundException if it doesn't exist: internal implementation choice, still displays a 404.
  * Smallhash regex has been rewritten.
  * Unit tests update
