Got rid of all the stuff related to GUNID hex-to-int conversion.
Commented out lots of functions that are either not in use or will
no longer work.
Pypo: made things more generic and pluggable, added documentation.
Added the PHP scripts to serve the right info back to pypo.
it can work with either OBP or Campcaster. Added the liquidsoap
binary. Started to add the PHP API scripts to send the correct data
to pypo (those these are not pretty - all one-off scripts for each
API command). Added Zend to the default path.
