Add context support to RDFS::Resource finders

[michael]

Add the ability to specify context when using RDFS::Resource finders.

ex:
context = RDFS::Resource.new("file:filename.nt")
SIOC::Post.find(:all, :limit => 10, :offset => 20, :order => DC::created, :where => { SIOC::has_container => forum, DC::author => author_id }, :context => context )
SIOC::Post.find_by_SIOC::has_container_and_DC::author(forum, author_id, { :context => context, :limit => 10 })

For the /find_by_/ form, take an optional hash which accepts all the options that RDFS::Resource.find accepts

Thanks. the hash with all the options is a good idea, I'll try do implement it soon (it's not much work, I just need to find the time).
