Luka's Scripting Utilities

Updated the scripting utilities to:

• improve documentation
• streamline implementation and add a bunch of new classes and utilities
• implement new wrapper class for shaders

(shaders only available at experimental branch of MKXP here: https://github.com/luka-sj/mkxp-z-ext/pull/3)

• Added a new function .all_dirs to the Dir class to list all the subdirectories in a specified directory.
• Added a new function .find_dir to the PluginManager class to find the root folder of a registered plugin.
• Fixed up issues with Hash deep merging.
• Made all the animation contents of the custom classes be FPS agnostic.
• Moved the EBDX PBS interpreter to the Env module.

Added lots of new utilities in preparation for the EBDX release. More notable features being the new CallbackWrapper as well as File.runPlugin. A bunch of other functions have been to some RGSS classes such as the Color class to be able to fetch specific colors without manually instantiating the whole object.

Compatibility for Essentials v18. This release makes the Scripting Utilities incompatible with the older releases of Essentials. Comes with new functionality as well as renames a lot of currently existing functions, so scripts depending on this one are more than likely to break. In case you want to download the v17 and below compatible version of the Scripting Utilities, you may still get it from the History tab.

Added a File.decompile function to the utilities to extract all the scripts from an .rxdata file into a desired directory
Added a .swapColors function for both Bitmap and Sprite classes to replace matching colors.

Updated the script to include even more functionality used in new systems like the EBDX. Will be absolutely necessary to have this script moving forward.

Script now comes with a versioning constant so that plugins can make sure your system is running the proper version of the Utilities script.
