tests: Add a new test runner
This is supposed to do matching tests, but can be used to do a lot of
things. It contans the following files:
configure.ac | 1 +
tests/css/Makefile.am | 2 +-
tests/css/matching/Makefile.am | 29 ++
tests/css/matching/simple.ref.png | Bin 0 -> 93 bytes
tests/css/matching/simple.ui | 20 +
tests/css/matching/test-css-matching.c | 636 ++++++++++++++++++++++++++++++++
