sfeed_content: allow to set HTML converter with env variable

This makes it a bit more easy to reuse the script and makes the run-time
dependency on lynx more optional.

For example with w3m:

	SFEED_HTMLCONV="w3m -I UTF-8 -O UTF-8 -T text/html -dump" \
		sfeed_curses ~/.sfeed/feeds/*

(of course this can be set in a wrapper script or shell profile too)
