ItemPanel modifications

Changed ItemManagerPanel to more closely resemble SceneManagerPanel.
Created the Edit Item Window and have it launching now.
Updated Scene/SceneManager/EditSceneWindow

EditSceneWindow:

Can now edit labels for connected scenes.
Can now remove connections from a scene

Scene:
Added a modifyTagByIndex function that takes in the index of the label
being modified and what it was modified to.  Changes the tag to the
specified label.

SceneManager:

Editing a scene and pressing save won't cause a name conflict

Lots of changes

Added the ability to add items to a scene.  Functionality not yet
available, but user will be able to choose an "unlock item" that the
player will require to enter the scene or a "drop item" that drops on
the scene, which will be added to the players inventory as soon as he
views the scene.

Added an additional column to the SceneTableModel that shows the names
of the items (if any) that is connected to the scene.  Updated the view
of the SceneTableModel to be more friendly with the data types received.

Various bug fixes.
