Drill / Professionalism
- Increased the natural decay of professionalism from -0.033 x level to -0.05 x level

- From game start everyone has a slight penalty to Drill, but gain bonuses as institutions are embraced ending up at 140% efficiency after embracing Enlightenment

- Changed up couple of advisors - removing the one giving Reinforcement speed, so that the Army Reorganizer now gives +20 Drill efficiency and the AI will be likely to pick him if at peace & the country has embraced printing press. Further tweaked the AI priority in picking MIL advisors to be more intelligent. (Im considering a seperate mod for this, for all advisor types)

- Reduced the penalty to professionalism by 4/5th from hiring mercenaries, as this caused some AI countries to tank their professionalism completely.
