www/angie-console-light: New port: Angie Web Monitoring Panel

Angie Console Light is a lightweight, real-time monitoring interface
for www/angie.
The panel uses the native angie api and only consists of a handful of
files which are put into ${WWWDIR}, so the port is just a more
coventient way to put the contents of the tarball into
"${PREFIX}/www/angie-console-light/".
