Version 1.3.8a

- Renamed Extended tech Tree to Extended Tech Tree Mod in preparation for the upcoming patch and because it was already named that in all but name (just making it official now).
- All sulfur powered thrusters and hyperium powered thrusters now feature a very limited backwards thrust to aid in agility for the smaller craft these thrusters are meant to be used for.
- Unified the densities of all durasteel armor pieces (thanks for reporting)
- Made some other preparations for the next patch (particularly the resource collector beam ranges are relative now to prep for next patches manipulator beam range buffs).
- Some strings description improvements.
