Multi-Rename Tool: Automatic Resize TabStop option.

[Balderstrom]

TC's FilePanels and Custom Columns have the option to AutoResize fields based on the Window size. Primarily useful for automatically resizing the "name" tabstop when restoring or maximizing a TC Window.

Similiar behaviour would be most welcome for the MRT. The "Old Name" and "New Name" TabStops could autoResize based on it's given window size.

Much like TC's main window, the MRT tabstops cannot resize when double-clicking on the separator between tabstops, either. And need to be manually dragged.
