Use Glib string interning (quarks) to make Path/URI operator== very fast.

This avoids a ton of string comparison overhead in Ingen when setting various
properties (e.g. "ingen:value" was compared several times every time a port
value was changed, now this is just a single pointer comparison and the full
round trip of a value change does no string comparison at all, but is still
property based and RDFey).
