Mindmap v1.0.0

This application is basically feature complete (in my opinion), and ready for 1.0 release. I can think of a few small tweaks that I might make in the future, but it basically does what I want it to do.

The main restriction is that it's designed to run as a desktop app and not a web server. To support that I would need to really overhaul the usage model (accounts, sign in and out, multi-tenant support, other security features). I might do that in the future, but I doubt it would happen soon.
