Dynamic prompts

Suggested feature for custom prompt/Gold users: **Dynamic prompts** By including a specific syntax in the prompt, e.g., `{option1|option2|option3}`, when generating the AI would randomly apply one of the options. By using `{1-3$$option1|option2|option3|option4|option5}`, when generating the AI would randomly apply one, two, or three of the given options. And so forth. For example: `{close-up|full body} shot of a {French|Japanese|Italian|Irish|Congolese} female {queen|wizard|fashion model} with {red|pink|blue|white} {short|long|braided} hair, {1-2$$raining|fog|sunshine|wind}` This functionality exists as a free extension for SD, so perhaps it would be easy to add to PornX.ai?
