Bringing back more classes and races

[Toma400]

Pre-alpha 3(b) content is minimised on race/class part on purpose, as this would delay the release for very very long time.
But, since this makes BRPGS 3.0 very incomplete, there is a need for remaining classes and races to be brought back. Not necessarily in their old form, since whole class/race system should be rebalanced, but this is call to bring some of those back in pre-alpha 4.

This will be also good balancing task for pre-alpha 4, since all current "todo" is related to programming, not narrative part of IoA.

This is not going into IoA anywhere soon, for many reasons. Unbinding milestone because at earliest I will think of it on pre-alpha 6 I guess.
