Inc. CxxTest utility through initalize_project.sh

If CXXTEST env. variable is not found, it clones CxxTest version 4.4 to
utils/cxxtest, and applies a patch utils/patches/cxxtest.191addd.printer.patch
which formats the tests output nicer, as well as does timings.

Example output looks like:
TestSDL::testAllSDLRAII       (532 ms) [ OK ]
