Write an Article on "Plugin Handling"

[ilexp]

Summary

Write a wiki article that deals with how Duality handles plugins and plugin reloads in the editor. This came up in a conversion on the chat, see here:

Analysis

• Core and editor plugins
• How they are loaded
• How they are re-loaded
• In which cases is a restart required and why
  • Why both need to be re-loaded when B depends on A and only A changes.
  • Why a restart is required on dependent reloads.
  • Why a restart is required on editor plugin reloads.
• Approaches to reducing the frequency of restarts.
  • Define a common, infrequently changed "base" plugin A, and let core plugin B and editor plugin C depend on it, but not on each other.
