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.
Merge branch 'sabe/strength' of https://github.com/HabitRPG/habitrpg-shared into develop
fix(drops): Ratchet up base chance some more

Ups the base drop chance to an expected 15% for typical tasks, brings back diminishing returns for super bonuses, reduces effect of checklists. Should be acceptable to most people?
