v0.3.0

This release does not contain any major API changes, however enough internals have changed to justify a point release.

• The kvdi-proxy has been rewritten as a more lightweight TCP/TLS server (instead of a HTTPS/Websocket server). Until now, the proxy has not undergone many changes, and the images have been largely backwards compatible. However, due to this shift, older versions of kvdi will not work with this proxy.
• A lot of UI plumbing and minor bug fixes
• I've started a CLI client for kvdi called kvdictl. It is not complete, but the goal is to have it serve as a useful utility for quick operations or gathering debugging information. When it is more finished I'll begin publishing binaries alongside releases.
• Very very experimental QEMU support is available via the Templates API. A lot of things don't work still (most notably, dynamic display resizing), and the SPICE support does not work at all yet (but VNC does). But there is enough of it there to make it available so people can at least start to play with it if they want.
