[openvrml-develop] Spirit parser work nearing completion

[Braden M. <br...@en...>]

As of my most recent checkin to the OpenVRML-Spirit-BRANCH, I think the
Spirit-based parsers are as good as or better than the ANTLR-based ones.
That is, as far as correctness is concerned, anyway. The Spirit-based
parsers are slower. I think it will be possible to improve their
performance; however, I am inclined to defer such optimizations until
after 0.17.0 is released.

I suspect my next checkin to the branch will remove all the ANTLR stuff
(which is presently just #ifdef'd out), after which I'll proceed to
merge this stuff onto the trunk.

Once that's done, the only thing I consider blocking the 0.17.0 release
is bug 1718762 (USE'd instances are not rendered on Windows).
