Use less(1) options to negate the need for a useless and lame shell func.

Use less(1) options to negate the need for a useless and lame shell func.

	* etc/pkgusr/bash_profile (LESS): Add 'F' and 'X' which will allow
	getting rid of that silly less-or-cat() shell function.

	* etc/pkgusr/handy_funcs (less-or-cat): Removed.
	Update all functions/aliases to use less instead of less-or-cat.
	(showinst,showgen,instg): Pipe output through less.
