Hi!

This patch fixes a crash when 'tui reg' commands are used in the non-tui mode.  Following
the 'layout' and other tui specific commands, it now switches to the tui mode and makes sure
the tui register window is visible.

Committed on 6_1 and mainline.

	* tui/tui-regs.c (tui_show_registers): Make sure the TUI is active
	and switch the layout to force a display of register window.
