Merge branch 'master' of git://github.com/bendiken/rdf
fixes for inferable
fix for the inferencing
first version of inferable works
merge with latest bendiken/rdf
Added a link to the parsing/serialization tutorial.
Update RDF::Writer#dump to allow arrays of statements
Implemented RDF::Repository#supports?.

Subclasses should override this in case they don't provide the standard repository feature set (for example, if they don't support statement contexts and named graphs).
Added notes about the ordering being undefined for most methods in RDF::Enumerable.
Fixed the version numbers in YARD @since tags.
Improved RDF::NTriples::Reader.unescape with support for \uXXXX\uXXXX surrogate pair decoding.

While the N-Triples specification does not allow surrogate pairs (Unicode code points U+10000 and above should be encoded as \UXXXXXXXX escapes, not as surrogate pairs), they are nonetheless frequently encountered in the wild (e.g. in the DBpedia 3.5.1 core datasets) and hence worth supporting.
Fixed RDF::NTriples::Reader string encoding issues on Ruby 1.9+.
Improved the duck typing in RDF::Writer#uri_for.
Bumped the RDF::Spec and YARD dependencies.
Bumped version to 0.1.10.
Added a link to Yehuda Katz's blog post about Ruby 1.9 string encodings.

Improve RDF::Format content type handling.

The content_type method takes optional aliases, to handle
formats where there is a canonical MIME type, but other
former or commonly used MIME types, such as 'text/turtle'
with other previously published types of 'application/turtle'
and 'application/x-turtle'.

The content_type method without arguments retrieves
content types claimed by the invoking class as an array
where the first element is the canonical type and
following elements are alternates.

For the latter case, content_type is no longer a
protected method.
Added Pius Uzamere and John Fieber to the contributors list.
