Remove make_command_window

This unifies the creation and re-initialization cases for the command
window.  When this is done, it becomes clear that make_command_window
isn't needed -- it can be replaced with a simple "new", so this is
removed as well.

	* tui/tui-layout.c (make_command_window): Remove.
