v0.8.0

• Minor breaking change in the CLI: memsparkline will process the options -h/--help and -v/--version like other options. This means they must be given before the first positional argument. These options were special and processed in any position. It was supposed to make help easier to access, but in practice it caused problems more than it helped. What this change means is that the option -h in the command memsparkline ls -h used to make memsparkline print help and exit; now -h is passed to ls.
