LibPDF: Switch to automatic ref counting, fix memory leak

Browse source 
At least `Value::operator=` didn't properly unref the `PDF::Object` when
it was called. This type of problem is removed by just letting `RefPtr`
do its thing.

This patch increases the memory consumption by LibPDF by 4 bytes (the
other union objects) per value.
