Enable/disable parameters and their dependancies

[calebsheridan]

Suggestion for UX:

1. Allow parameters to be explicitly disabled (which results in using their default values, regardless of the input value).
2. If there are dependant parameters (e.g.: Mirostat must be enabled for Mirostat-Tau and Mirostat-Eta), the dependant parameters respect the parent's status.
   3. Promote System Prompt from Settings Modal to Form Grid (it is the only parameter in Settings). By default, disable system prompt.

Disabled params will appear gray and only display on one line:

<title> <tooltip> <toggle>

Enabling params will appear normal and display on three lines:

<title> <tooltip> <toggle>
<input>

Thank you for the suggestions.

I'll definitely consider #3 first, as it's the less messy to implement.
To disable the system prompt all you have to do is to leave it empty.

If the suggestions are ok, we can leave the issue open until someone can work on it

Done.

System prompt promoted to main form as of v0.4.0 (plus the changes you submitted and other minor updates)

Thank you for the input and PRs.
