Added ttkConversion.py, which is a temporary file while I convert the UI to use Ttk instead of just Tk.
Once working this will be merged into UITesting.py and MainUI.py, and eventually into MainBranch

Added rename functionality
Added modifier keys when hovering over file operations buttons
	"Save" + Shift = "Save As"
	"Save" + Alt = "Rename"
	"Open" + Shift = New
	These will be reflected in the keyboard shortcuts
