Introducing GUI Editor into Master

[msDestiny14]

The GUI Editor will be new tool to allow users to create and modify GUI for scenes. It will be a standalone editor similar to NME. This is the foundation PR to officially merge the beginning working codebase into master. This is not a finished editor.

The GUI editor was created by using the code base of NME, removing the node material specific code, and then adding specific features for the gui editor. While I tried my best to remove most of the node material related code please let me know if there is any extra remaining.

Current features:

• Launch GUI editor in local dev mode.
• Drag and drop GUI elements onto a canvas.
• Select and move individual GUI elements.
• Modify properties of selected GUI elements.

Important Files: These are the files with the most work done.

• guiNode.ts – Contains the class responsible for holding all GUI information for each element.
• workbench.tsx – Contains The class responsible for handling all the GUIs in the center of the screen.
• workbenchEditor.tsx – Contains the class that holds the workbench and other components for the entire editor.

TODOs:
You will see various places in the code with marked TODOs for future work.
Property tab component is incomplete and has several chunks commented. To be implemented later this week.
Includes property grid components that will be removed once the shared UI work is complete.
Additional comments need to added.

Thank you in advance for your time! :)
