Added functionality

Closing the main window via clicking the X will now prompt the user to
save.

Clicking Edit Scene now has the skeleton code that opens the Edit Scene
Window when clicked.  Currently, it just passes in a blank test scene,
but should have functionality changed to take in the selected scene
(when scenes become viewable).

So much stuff

Created a WindowComm class to handle simple interactions with the user
that only require a yes or no, or simply a message for the user.

Designed the edit scene window and added functionality to a few of the
buttons (all buttons have action handlers, but not all action handlers
actually do something useful).

Clicking add scene or edit scene will open the scene window and disable
buttons on the SceneManagerPanel so that multiple are not opened.

Opening the edit window will load necessary information from the
selected scene into the window.

Added an ArrayList for connected scenes within the Scene class, also
added an ArrayList of labels that corresponds to the connected scenes.
(Each connected scenes label will be the message displayed to the player
of the game to move to that scene).

Have not yet added error checking to ensure that every scene has a label
attached.

New class, A lot of functionality added

Added a new class: AddConnectionWindow - used for when a scene is being
edited and the user has clicked on connect a scene.  Displays a list of
all scenes, the user may choose one.

Added a lot of functionality to EditSceneWindow.
Adding a scene will now actually add a scene, you can remove scenes and
edit selected scenes.

Current known bug:  Editing a scene and selecting save causes the
manager to think it is adding a new scene that has been edited into the
system.  This will cause a name conflict, as it is conflicting with
itself.  To fix, just make the scene manager check to see if the
requested scene to add is already contained within the list.  If it is,
check all names except for its own.

Added a few functions to scene, each scene has a flag now that
determines whether or not it has connections to it.  Later functionality
will check to see if it can actually be reached.

Various other bug fixes, probably various other bug creations too.
