UI: Replace big options button in file browser

The big options button in the lower left is now gone, it's replaced by a
smaller icon toggle button in the upper right.
That means I could also remove code for the region we had just for this
button.
I also added versioning code for the removal, to make sure the region is
removed cleanly when reading old files.
