Better integration into "extra networks" tab

[Learwin]

As mentioned in #26 it would be really useful to further enhance the integration with the extra networks tab.

I have a few ideas that would improve usability, productivity, organization, ease of use and workflow:

• A button on each model's card (in the extra networks tab) that takes you to the details of the Model in the organizer
  

• If no details for that model exist open the "Add model" prompt
  

• The ability to search/filter by groups in the Extra Networks tab, like it is possible in the model organiuer
  

• Ability to click on a model card in the organizer tab to copy the positive prompt and or negative prompt to the clipboard.
  It would be very useful to be able to get the stored positive and or negative promps from a model be it with a button, a rightclick context menu or other means.

• Extend the cards in the Extra Networks tab to allow negative prompts being added to the negative prompt field. (Right now you can only add positive prompt tags as metadata)
  (This would probably be something for WebUI itself but would be nice to have if it were to be added by an extension)
  As you can see in the image, there is only a field for activation text, but it is quite common for a model to specify negative prompts as well. When I now click on the card in the extra networks tab the activation text will be added to the positive promps. (Maybe integrate the negative promps that can be specified in the organizer)
  

I do not have experience with javascript or python but I'll see if I can try to make some of this happen.

Once AUTOMATIC1111/stable-diffusion-webui#14475 gets merged negative prompts can be added by clicking the extra networks lora card.
It's all merged into web ui

I've also started work on adding features mentioned above.

1. You can now press the button on the cards in the extra networks tab to immediately get taken to the add/view record view in the organizer
2. Configurable option to import existing json data from extra networks and prefill values inside the add record screen.

Currently working on adding the ability to click cards in the organizer tab to automatically add positive and negative prompt together with the lora activation keyword. Once I finished this I'll open a PR

See #75 for PR of my ideas.
