bin/fl added, lh reworked, opener renamed, data/applications removed

bin/
	fl: finds links, sends list to dmenu so user can choose one to copy to the
	clipboard
	lh:
		replaced sed invocations with lstrip() invocations
		redir handling changed to function findredir(), which loops over curl's
		output, only outputting location urls
		changed case statement to look for .extensions instead of the end of the url
		local files are now sent to bin/op for processing
		mpv given --no-terminal flag for no output instead of redirection shit
		similarly, sxiv is given -q (and -p to not cache)
	op:
		formerly opener
		changed error message to be more portable
	prompt:
		removed help text
	pw:
		doesn't need to be in a variable
	rsschk:
		redesigned after an eternity
		uses a modified re_urls, looking for .rss and .xml urls
		generally smaller
	shenv:
		uses ${var:=val}
		specifies /bin/sh
	xbg:
		removed .fehbg handling
config/
	aliasrc:
		e and v set TERM to xterm-256color, otherwise vis freaks out
	cwmrc:
		urgencyborder color added (with color1)
		ungroupborder changed to color5
		program list removed
		4-Return set to $TERMINAL
		4S-r rebound to restart
		4-X set to $LOCK
		prompt binds fixed
	dunst/dunstrc:
		icons disabled
	ksh/functions/l.:
		changed to ksh function
		for non-current directories, changes there in a subshell and uses that
		current directory, sending an error message if the directory doesn't exist
	lf/lfrc:
		cmd open removed
		cmd ttmsh fixed
	shrc:
		removed ALTSCR
		added OPENER=op
		IRC_SERVERS_FILE removed
		TODO changed to correct path
		GOCACHE and GOBIN added, self-explanatory
