Phantasy Star II 0.0.3

Mainly fixes in this version:

• Tech shuffling now properly assigns all possible techs instead of leaving some out
• Having the RECORDER at odd times shouldn't cause conversations loops at the Central Tower anymore

But one added feature:

• randomise_techs is now a choice of Vanilla, Shuffle and 'Sensible Shuffle'
  • Sensible Shuffle performs Shuffle then sorts them by relative strength, so you should get weaker techs earlier
