Add GuiHandler

GuiHandler is not in fully working order. The HideOthers function
prevents all toggle functions from tweening their Frames off-screen.
Implement new comment block to all documented scripts
Remove Readme files from subdirectories
Add double equals between all brackets in main comment blocks
Change _G.config to _G.ready in all scripts

_G.config is now the path to the Configuration object, _G.ready
is now used for allowing other scripts to know when Global variables
are ready to be used.
