Finish Plugin Interface

[octalmage]

Introduction

Currently there is a very basic API implemented using WM_COPYDATA. Extend this to support registering plugins and bidirectional data.

Tasks

• [ ] Add support for installing plugins.
  • Plugins will be installed in the plugins subdirectory.
  • The plugin package will either include an .ini file with details about the API window, or we will assume it's the same as the .exe filename.
  • Either allow the plugin to subscribe to messages using the .ini, or send all messages to each plugin. Currently I'm leaning towards sending all messages.
• [ ] Send each plugin their subscribed messages.
  • Desktop changed.
• [ ] Implement additional methods.
  • Send window to desktop.
  • Get list of windows on desktop.
