Implemented optional header-only mode (still need to do a couple of fixes for rare compilers, but it seems to work on the majority of configurations). Tests work in header-only mode, but testing is not enabled yet (still a bit more work to be done, and compiling header-only tests is up to 4 times slower, so we can't test more than one-two configurations per toolset)
