Generalise tagger view to all scraping sources

[WithoutPants]

This is a significant rewrite of the Tagger code. Changed so that common data and functions are consolidated in a context, and generalised so that it supports non-stash-box sources.

The header section has been redesigned to allow selection of the scraper source, and options is moved to a button on the right:

Qualifying sources are stash-box instances, scene scrapers that allow string queries, and scene scrapers that allow scraping via fragment.

The scene card has been changed to add a Scrape by fragment button. This is the same as the old Match fingerprints button but for a single scene - it will scrape by fragment for supported scrapers. This button is not shown if the current source does not support scraping by fragment.

The stash-id is shown. The presence of a stash-id no longer prevents querying on the scene.

The behaviour of the performer and studio buttons have been changed. When create is clicked and the dialog is confirmed, the applicable object is created instantly and the display changes to show that it is matched to the new object.

For stash-box sources, a disk button is shown to the right of the selector. This allows linking an existing performer/studio to the selected one - by setting the stash-id on the object. This linking is no longer done when saving the scene. This button is not shown for non-stash-box sources.

When querying scenes using a keyword, only summarised results are returned. As such, when a search result is clicked on, the system resolves the scene, in the same way as doing in the scene edit page.

The Scrape All button is shown only for stash-box and sources that allow scraping by fragment. For stash-box sources, it operates the same way as the previous Match fingerprints button. For scraper-sources, it sequentially searches each scene one by one, populating results as each request returns. This process can be stopped by clicking on the stop button, which appears when clicking on the Scrape All button.

Looks and works great.
A minor regression, when using the stash-box scraper it shows results even for scenes that have a stashid and allows you to save which then results to a 422 error

{
   "errors":[
      {
         "message":"unknown field",
         "path":[
            "variable",
            "input",
            "stash_ids",
            0,
            "__typename"
         ],
         "extensions":{
            "code":"GRAPHQL_VALIDATION_FAILED"
         }
      }

With the current scene tagger scenes with a stashid can not be modified in the tagger view

To reproduce

• go to scene tagger (stash-box as a source)
• add scene filter Stash ID is not NULL
• scrape all
• select any of the matching scenes and hit save

Thanks, this should now be fixed.

Noticed that running with the Auto Tag scraper looks gross. So there's still so work to do there.
