boost_test_jamfile with better parsing

[HDembinski]

I started working on an improved Jamfile parser for boost_test_jamfile.

The new version should recognize the following tests

test-suite foo
[ run some_test.cpp ]
;

run
  some_test.cpp
;

run some_test : my_arg ;

I think it would be much easier to write the parser in Python and call it from CMake than implementing the logic with CMake capabilities. Would that be a show-stopper? And is it really useful to have an imperfect Jamfile parser in CMake? An alternative is to provide a Python script which generates the whole CMakeLists.txt from an existing Jamfile.

+ Still easy to convert simple Jamfile files to cmake
+ You can edit special cases not handled by the parser
- Needs to be run manually

The last one should be handled, since I added support for test arguments to boost_test. I however consider the current "parser"'s simplicity a feature, because it allows me easily to skip tests I don't want boost_test_jamfile to handle - I then write them by hand in CMakeLists.txt. As long as there are few exceptions, it's not a burden.

It would be easy to also handle [ run test.cpp ] I suppose, but this may not be desirable if the test suite is declared explicit, which is why I've left it out.

Yes, my bad.

I thought of adding a BLACKLIST argument for tests that should not be handled automatically. But I am unsure whether it is worth spending more time on making the jamfile parser more sophisticated.
