[patch] don't display very-low-strength APs.

[Robert Love <rml novell com>]

As featured in several award-winning news reports[1], Cambridge has a
lot of wireless networks.  I finally got strength working on the Cisco
AiroNet card, and I see that many of those networks have no strength
whatsoever.

My Mac only shows a few access points, effectively filtering the crappy
access points out.

Attached patch filters out access points at or below 1% strength.  In
addition to not displaying worthless AP's, this keeps the number of
transient networks down--less falling in and out of display.

The one concern is if any wireless cards with broken strength detection
return zero for all strength.  I've only seen 100% returned, so I think
this is okay.

If so, may I apply?
