-Added an Animation Editor for textures in the "textures/blocks" and "textures/items" folders (besides the clock and compass) and an "EDIT TEXTURE ANIMATION" button.
-Within the animation editor, there is a "Set Bulk Animation Speed" function that sets the entire animation to a set frame speed.
-Improved the drag and drop function.
-Changed some pop up dialogs to child dialogs to prevent multiple extra windows.
-Changed the "EDIT AUDIO" button text to "EDIT MUSIC CUES" to describe the Audio.pck functions more accurately.
-Changed the main tree's double click event to a NodeMouseDoubleClick event to prevent a rare crash and optimize that event's code.
-Adjusted the max display size for large images so that the meta tree would no longer be blocked.
