Add 'fill selection' command to grid map editor

This commit adds a 'fill selection' command (shortcut: shift+f) to the
grid map editor, making it easier to block out large parts of grid maps.
The new command is equivalent to the existing 'clear selection' command
except that it fills the selection with the currently selected block
instead of the empty grid cell.
