New release 0.1.0 with plugins

pyAlarm just got some significant improvements. Now it supports basic plugins. Still needs a bit of work, of course, what doesn't? Sorry, but now you have to download two packages. Download the base program and the plugin package, install the base program *first*, then install the plugins. If you download the source tarball, you get it all at once, so just run setup.py from the root, and then cd to plugins and run setup.py there.
