Update v1.0.0.0 - Release (ish)

I have planned to release this on Steam today, but it's delayed, like it wasn't happened before but yet again. Because of my overconfidence and that Archangels won't dance without a music. I've never revealed the release date before, because I am planning to launch this as soon as it ready.
However, I managed to make a release version of demo. This one is not so big and plays a formal role to demonstrate the state of the game.

Changelog:

- Updated readme files
- Temporary removed tools
- Added end credits
