Popups are finished! (almost)

After a little bit of work, a popup system (which I gotta say is written kinda well compared to all the other code) is in place!

Currently, there are:

• Exit Confirmation Popup
• Save File Dialog
• Load File Dialog

One last thing is still missing though: The please press a button popup for inputs (,).

Technical Details

The popup system works by using a sub-struct inside of the global state struct (state.popup). It contains data such as whether a popup is active, if it accepts text input and handlers for drawing and the confirm button.
 
There’s a base func (create_popup_base()) that draws a new basic outline for the popup. After that, only the contents of the popup get refreshed via the custom handler set via setting a function pointer (state.popup.refresh_handler).
The popup also “captures” input. There’s a seperate if for state.popup.active before the main input validation which processes inputs and then skips the normal input processing.
