squid_redirect (adzapper)

Many patterns were updated since the last public release.

A bunch of updates were made, including some overzap fixes.

A security fix was made for pathological behavior
for certain URLs. A new ad class was added for
text-only ads, which are off by default.

This release features a new "stand-alone" mode not needing a
Squid or Apache proxy, which is helpful on very small boxes
but not optimal if you have the resources for a squid. There is
new Apache2 proxy mode support, a new "URL?NOZAP"
handler to bypass the zapper by hand from the browser for a
single URL, and the usual collection of pattern updates.

This release adds rewrite rules, allowing things like getting the "printer friendly" version of a Web page; several news sites are set up for this, though that pattern class is off by default. There's also the usual large number of rule additions.
