Support categories and auto-complete for tags and categories

[TheAnachronism]

Clear and concise description of the problem

As far as I can see, this extension isn't able to specify which category the added bookmark should have.
If briefkasten itself is capable of that, this extension should also be able to do that.

Also, is it possible, for an autocomplete of tags and categories?
Would make adding links quickly far easier.

Suggested solution

Also have a category field above the tags field in the extension screen.
