Support POD conversion via *.spin pointers

Support *.spin pointers in addition to *.rpod pointers for external POD
files.  The command-line flags used in *.rpod pointers are replaced by
the title and options key of the *.spin file.  *.rpod files are
deprecated and support will be removed in a future version of DocKnot.

Add spin_thread_output method to App::DocKnot::Spin::Thread, intended
to convert thread to HTML as part of a conversion pipeline of a
non-thread input file, while still using sitemap information and
generating the page footer.  DocKnot now depends on Path::Tiny.
