v0.08 Pre-alpha release

The general service-management capability of Dinit is ever increasing. This release adds a "shutdown" subcommand to the dinitctl utility, adds a few new service options, tweaks default build options, fixes some bugs, adds to the testsuite, and more. It updates the bundled Dasynq to 1.1.0, meaning it may be possible to build Dinit on systems that have neither epoll nor kqueue (but which have pselect). Build has recently been tested on OpenBSD and FreeBSD as well as Linux.

It is of course still a long way from finished, but it seems to be stable right now so I'm cutting a release.

The next release will likely be versioned as 0.1.0 and Dinit will move to "semver": after that will be 0.1.1, 0.1.2 etc, until 0.2.0 (or beyond) and eventually 1.0.0.
