Convert into gradle plugin

[Gamebuster19901]

Convert WilderWorkspace into a gradle plugin instead of an application. This will be a complete rewrite, so the next version will be 4.0.0.0

Blocks #23

The gradle plugin should:

• An initial setup task that:
  • Copies the game files from the default game location
  • Decompiles the game files to a decompilation folder
  • Decompiles line mappings for jars
  • Remaps the decompiled jars using the created line mappings
  • Configures IDEs to use decompilation folder as a source
• Update game task that:
  • Copies the game files from the default game location, overwriting files in the current workspace
  • Decompiles the game files a decompilation
  • Configures IDEs to use decompilation folder as a source
