po: Removed tracker-enumerator.c from POTFILES.in

It was added to fix distcheck for the external-crawler branch accidentally as
part of other fixes too
all: Switch out GSettings "schema" property for "schema-id"

Was causing unit tests to fail and made distcheck impossible
ontology: Removed duplicate nfo:depicts and correct domain/range

Previously nfo:depicts was defined, but not nfo:depiction, because the spec
was in draft at the time.

The domain/range bug was a copy/paste error

All noticed on make distcheck
docs/reference: Use FULL paths for DOC_SOURCE_DIR to avoid undefined warnings

This only occurs during distcheck because the path is not relative any more,
but it should be referenced from $(top_srcdir) anyway to avoid these warnings.
Release 1.1.0
