[2022-07-30] Spine runtime integration, revamped ask() function

I have been working on a new Satania skin for quite some time, and the limitation of Castle Game Engine (CGE)'s Spine runtime implementation prevents me from making a lot of advance animations. So in past month I have been working on an official Spine runtime component for CGE, and this update is the fruit of past month's works!

• Adds support for official Spine runtime 4.0. See https://github.com/Kagamma/satania-buddy/wiki/Create-new-character#supported-spr... 
• Revamped ask() function, allows to use HTML to display contents in ask dialog. For example:
  ask('
  <font color="red"><b>Are you sure?</b></font><br />
  <a link href="Yes">Yes</a><br />
  <a link href="No">No</a><br />
  ', 250, 80)
  Will create an ask dialog like image below:
   
  The answer can be retrieved by calling answer() function.
  See ask() in https://github.com/Kagamma/satania-buddy/wiki/Scripting-References-&-APIs#satani... for more information.
• New Interject menu, showcase on how to use ask() function.

Hopefully with this update now I can continue work on new Satania skin without having to worry about compatibility & limitations.
