Currently, when you untick a todo or daily, there's a chance of a critical hit. This prevents that.

fix(text): Update descriptions for recent changes

Changes the English language text for the STRength attribute and Warrior class to take into account revisions to stats and drop chance scheme. Also fixes an inaccuracy in the CONstitution help text and updates the Buffs description to include the possibility of buffs from achievements (e.g. Perfect Day).
fix(quests): hedgehog fix alignments
fix(drops): Boost base drop chance

Initial feedback from the drop chance overhaul was that non-minmaxed characters had their drops severely curtailed, while tricked-out Rogues with enormous streaks were still scoring drops every time. Lots of complaining ensued! This commit doubles the base chance, establishes a minimum base chance of 2%, and halves the effectiveness of the high-end offenders.
fix(strength): Remove threat reduction, increase crit chance

Tweaks the STR attribute's algorithmic effects. (1) Task "redness" no longer declines faster with high STR. (2) The 3% chance of a critical hit is multiplied by a percentage factor equal to STR. (3) The value of STR in dealing damage to bosses is increased by 25% (.5% instead of .4%).
