Updated PHP, added submodule

Added: @tekimaki 's Spyc as submodule
Updated PHP: now with --enable-ssh2! Repositories will also now be able
to be fetched securely. :)
Todo: The core installer must be re-written. The outside changes are a
huge affection. Threading needs to be implemented, Spyc needs to be
supported completely and ssh must now be accepted.
Stay tuned!
