revamped port dependencies

• if defined(BATCH) && defined(APSFILTER_ALL) every tool and filter supported by apsfilter will be installed (very time and space consuming)
• if defined(BATCH) only most necessary things are installed

If you want complete control over what to install, then don't
define BATCH or BATCH && APSFILTER_ALL, then please use the
new updated interactive method of building using dialog.

The configure script is now up to date, concerning tools needed/supported
by apsfilter and a little bit more explicite !

Thanks for Greg Lehey and friends for a vivit discussion, this
is the desired result I hope !!!
