Devnull Mod Gold: updates and discussion

[Rollo]

...and a synopsis of the above:
* new AI for temporal races: Xiati and Sallega
* lots of tweaks to other races that should improve performance
* fixed an exploit with Weapon Platform PD mounts and Reactive Armor
* improved weapon balance
* lots of new ruins techs, including the infamous Sci-Fi Canon Cannon
* graphical updates
* now supports both FQM (full implementation) AND classic Quadrants
* lots of tweaks involving to-hit chances
* revised mounts
* races with non-revised AI are now added very sparsely or not at all
* and more

maybe still to come (or in next update):
* higher levels of Engineering with nifty multipurpose components
