OSX binaries supported

With this release, binaries on Mac OSX can now be covered as well. The implementation relies on the LLDB debugger (programmatically as a library), so it should also be portable to other Unixes. The support is lightly tested so far, so there are probably bugs still around.

Other than that, there are a few fixes for Bash corner-cases, better detection of some ptrace events, and more fine-tuned configuration abilities.
