New autocomplete modes: 'Whole String', and 'Last Word'

    - New autocomplete matching modes: `Match Whole String`, and `Match Last Word`
    - Image Grid: View all images as thumbnails in an overview. Access it from the 'Tools' menu, or from the right-click image menu.
      - `Match Whole String`, This option works exactly as before. All characters in the selected tag are considered for matching.
      - Click an image to quickly jump to it.
      - `Match Last Word`, This option will only match (and replace) the last word typed. This allows you to use autocomplete with natural sentences. You can type using an underscore as space to join words together.

   - New:
-    - New tag list `Derpibooru`: Created from the top ~100k Derpibooru imageboard tags with additional filtering.

-        - Hovering the mouse over this indicator will display a tooltip showing the text path.
-    - The mouse wheel can now be used on the index entry to cycle through img-txt pairs.
