* keyboard.c (make_lispy_event): Added detection of double-click

	and triple-click events.
	(parse_modifiers_uncached, apply_modifiers_uncached): Same.
	(read_key_sequence): Coerce double-clicks to clicks, and triple-clicks
	to double-clicks or clicks, by analogy with drag events.
	(double_click_time): Added variable.
	* termhooks.h: Added multi-click event modifier bits.
