Pbf support

[IrlJidel]

src/main/java/com/yellowbkpk/geo/xapi/servlet/Filetype.java defines your Pbf writes as:

pbf("application/binary", "org.openstreetmap.osmosis.pbf.v0_6.PbfWriter");

However org.openstreetmap.osmosis.pbf.v0_6.PbfWriter class does not exist in either your git or master osmosis code base.
Did you use a different osmosis src tree for your pbf support?

I'm using your git osmosis src and have json suport working

After looking at osmosis pbf code I attempted to make the following changes for Pbf support

However I get for pbf requests I get:

HTTP Status 500 - I don't know how to serialize that.
