v0.42 Icon and fixes

1. Icon now has specifically drawn low res versions.
2. Application should now appear the first time the tray icon is clicked if launched minimized to tray.
3. Should now properly reconnect to SteamVR if it is restarted.

v0.36 There shall only be one

• Prevent multiple instances from being run at the same time, this to prevent chaos and confusion.

v0.35 Breaking changes

• One day later and I've redone the actions so it can be expanded painlessly in the future, it feels much better to have it this way, but it means any previous configurations are dead. Hopefully this won't happen again.
• Added default binding for Index controllers that actually bind to the available actions.
• Changed default appId to gray instead of red, it's not dangerous.
• Tweaked icon slightly.

v0.31 Fix bindings

Had left a non-existing action in the knuckles binding, this did not show up during testing, because SteamVR caches things? It's a mystery.

v0.30 GUI fixes

• Fixed window still being visible while minimized at launch
• Fixed row highlight not reactivating after finished recording mapping
• Increased window height
• Renamed bindings to mappings, to make it less confusing

v0.28 First public release

This should have all the basic functionality I had planned for the application. If you find any issues, please report those here. I'll be updating the readme momentarily.
