Introducing support for Web Start and Mozilla plugin from IcedTea6 1.9.

Note the feature is turned off by default because it adds experimental and
unofficial patches from icedtea.classpath.org.  You need to select WEB option
from config menu or define WITH_WEB variable to enable the feature.  Also,
note that a symlink for web browser is not created automatically with same
reasoning.  Thus, you need to create a symlink for your browser, e.g.,

ln -s ${LOCALBASE}/openjdk6/jre/lib/IcedTeadPlugin.so ~/.mozilla/plugins

Remove some stale comments in package message while I am here.

+This patch works around POSIX thread anomalies in the IcedTea6 plugin.
+Somehow Linux can use mutexes and condition variables uninitialized.
