Image Editor: Initialize Add Tile options from current tile

Previously, non-default alpha or float settings had be set manually.

With this change, the Add Tile and Fill Tile operators initialize
width, height, alpha and float from the currently selected tile
if it has a vaild ImBuf, otherwise from the first tile.
