Lua scripts

Previously Retro Graphics Toolkit has been static in nature this meaning that you were limited to what I have programmed in Retro Graphics Toolkit in regards to automated functions. For example I added an option to sort each palette row by either hue, lightness or saturation. Before I added this trivial feature despite it’s simplicity you could not that in an automated way in Retro Graphics Toolkit you would have to do it manually.

As of now Retro Graphics Toolkit uses Lua 5.2.3 (the latest stable version) so keep that in mind while writing scripts.

Also an API of functions is provided and will be defined soon.
