Request: Saving prompts as templates / styles

[Azathoth88]

As a user, I would like to be able to save the prompts I use as a template so that I don't have to enter them manually each time.

• I can use different templates
• Templates can be combined with each other
• When selecting a template, the text in the prompt is prefilled
• A template can contain positive & negative prompts
• Saving is done via a "Save as template" button
