Added distro-specific init scripts based on those used by NM (these are very experimental and likely broken in many cases).

Updated setup.py to pick which initscript to install based on the distro detected.
Updated MANIFEST.in to make sure launchdaemon.sh is included in the sdist build.
Fixed a bunch of crash bugs in tool detection system when tools are detected.
Made tool detection work correctly when "which" returns output if no match is found (as opposed to no output).  Eventually we might want to hardcode possible paths instead of using which at all...
Fixed some message formatting in the daemon.
Added some docstrings.
Added a pidfile system for increased initscript compatibility (sort of, it's somewhat incomplete).
