Hotfix for an issue with learning rolls and tax

Fixed an issue where attributes that don't have a tax property where
rolling NaN dice (defaulting to 1) when skills rooted in those
attributes were being tested via beginner's luck

Also, fixes a UI issue where the forte tax cap was incorrectly being
calculated in the spells section of the sheet.

Updates version to 0.3.2
