Flatter XP curve

[hcobb]

If per-session rewards remain at 60 XP then it's gonna take forever to add talents and attributes past the first few. The advantage of heroes of adding talents twice as fast as wizards just won't catch up with the wizard's starting pool of memory points.
The fix here is that adding an IQ point with XP (but not wishes) brings an additional memory point with it, and to flatten the XP curve to +200 per level like this:

• 33rd - 100XP (2nd session)
• 34th - 100XP (4th session)
• 35th - 200XP (7th session)
• 36th - 400XP (14h session)
• 37th - 600XP (24th session)
• 38th - 800XP (37th session)
• 39th - 1000XP (54th session)
• 40th - 1200XP (74th session)
• 41st - 1400XP (97th session)

So a ST 12, DX 12, IQ 8, Myrmidon who started with Sword and Shield talents would spend 4400XP to raise his stats to ST 13, DX 14, IQ 13, and then spend another 1500XP to add the final 3 memory points for Sword Mastery and Shield Expertise, by his 100th play session.
