v0.05: "works for me"

I'm bumping the version after cleaning up a few rough edges, but many more remain. I've been using Dinit as my system init (on Linux) for some time now and I've not had any major problems, but I won't feel comfortable recommending this to anyone else until I at least have a basic test suite implemented.

Documentation is in the README, and see the doc/linux directory for information on how to set it up as a system init. Executables comprising Dinit all respond to the "--help" command line argument.
