Allow web style and JAV title searching

[Flashy78]

• Updates the scene search table to allow for JAV titles by leaving in hyphens and colons. Previously you could only match JAV titles such as EMS-259 directly on the scene code field, now you can also directly match the title.
  • https://stashdb.org/scenes/59bbc814-7891-4d45-9afe-93e6ee225c03 cannot currently be found by searching FSDSS-685 because its studio code is empty.
• Switches to websearch_to_tsquery to allow users to double quote words as a search phrase and using the dash to ignore words.
• Changes the text search formats to all use english as the search configuration, since the default_text_search_config is english. That's what plainto_tsquery was defaulting to, and I added to websearch_to_tsquery to be explicit.
  • For scene code EMS-259, the to_tsvector('simple') would produce ems and -259, while to_tsvector('english') would convert it to em and -259, meaning they would never match. This is why searching for EMS-259 cannot find https://stashdb.org/scenes/c5cd9919-727c-41bc-bd66-d515a0c1b5cc
  • Dates don't appear to be affected by the change.
