Version bump 0.4.1; added support for SysV init.

Init script based on one from @blalor.

Retains systemd support for Fedora >= 14 or RHEL >= 7.
Removed '-bootstrap' from command args; it's dangerous.
Merge pull request #3 from tomlanyon/master

Added support for non-systemd init script, version bump, don't bootstrap by default.
