Inventory

Added Inventory / Backtrack
fixed conflicts

Fixed RunGameWindow conflicts
Fixed Remove Item Functionality

When an Item is removed, it now removes itself from any scenes that are
connected to it.
Added Pictures

User can now edit a file in /images/images.txt
If the user specifies an image in the format:

image name (can be anything the user wants)
imagename.extension (the actual name / extension of the image)

and ensures that these images are maintained within the same folder,
then the SceneManager will load these files on startup and the user may
select an image for each scene.
