PromptStack model

[Ivshti]

This model will be used for showing prompt modals to the user, such as:

• to ask the user if they're sure if they want to install an add-on
• if they're sure to open an external URL
• to show what's new
• to show advanced context menus on right click (will require different styling/custom popup position, but follows the same logic)
• to show subtitle controls

and others

PromptStack model that keeps a stack of user prompts that resolve to being closed or actions

It will handle a Msg: OpenPrompt { title, content, buttons }

title is a string title, content is a markdown string, and buttons is Vec<PromptButton>

PromptButton will have content, tooltip, onAction which is a enum PromptButtonAction { Dismiss, MsgAndDismiss(Msg), MsgNoDismiss(Msg) }

more than one prompts can be stacked (nested), hence the name PromptStack

we can use the prompt stack in conjunction with other stateful components, such as the subtitle picker; it will just use the promptstack for it's show/hide logic

this should be moved to stremio-seed-poc

[Ivshti]

disagree, I think it can be used in many stremio implementations and therefore it has a place in core

The logic is the same for all platforms, no matter how modals display (full screen or as a dialog)
