Object Editing

I mostly improved/added to the object editing aspect of the editor.  I changed the way the object editing worked and looked, of course you didn't know how it originally looked, but the new version is a lot nicer and easier to use.  I also started the entity editing for an object.  An object contains any number of entities (models, lights, etc.) and I started on the editing of those entities.  I also fixed some global variable problems that I had in the code, it didn't affect the result of the editor, but it's a lot cleaner code now.  I also added the ability for me to add a new viewport at any time anywhere on the screen, which will be very useful when I get the point of editing mesh properties, shaders, etc.
