Spiritus Astrum [P0-B14]: p1663: Towards Early Access

I have made many improvements to the game, and fixed many bugs.

The game balancing during combat has been improved, and I have made improvements to the physics code, and movement. I have improved the control system layout, and added basic joystick support.

The campaign story triggers have been tested and further improved, and I have added visible navigation paths to complex interiors to aid in navigation (Activating the in-game radar also displays any nav paths that are available). This makes it much easier for the player to navigate within interiors.

I also fixed a complex longstanding bug that was causing some items to rotate incorrectly when placed far from the player, as well as another bug with rotating the jetpack at certain angles.

I have also wired up several of the games unlockable abilities/traits/skills. Not all will be done in Early Access, but I am going to add as many as I can. The skills system in the game has also been tested and improved.

Finally, I have improved the weapon reload system so that weapons now reload automatically, even if ammunition is not equipped in the item slots. This makes combat and gameplay easier.
