Temporary hack to debug the MATE grammar.

Temporary hack to debug the MATE grammar.

Builds on my machines, physical and virtual, crash with an assertion
failure in the MATE Lemon grammar when parsing the MATE configuration
file in bug 12161 - on Mac OS X Lion with llvm-gcc, Ubuntu 15.10 with
GCC, and on macOS Sierra with clang.

Builds on the macOS buildbot do *not* fail.

So put the result of Lemon in the MATE plugin into the release tarball,
so I can compare it with what Lemon generates on my machine.
