prevent critical hit when unticking a task

Fixes https://github.com/HabitRPG/habitrpg/issues/2356

Currently, when you untick a todo or daily, there's a chance of a critical hit. This prevents that.
fix(drops): Overhaul drops to a percentage multiplier system

WIP. Initial draft of an overhaul to drop chance. Most important bits: (1) A modular system of percentage-based multipliers on the task-value-based initial drop chance. (2) Perception increases the daily drop cap by 1 per 10 points.

Fixes HabitRPG/habitrpg/#1922.

i18n(gems): update wording on buy-gems to remove "no ads": https://github.com/HabitRPG/habitrpg/issues/2416#issuecomment-35289915
Fixes #1528. Stores the currently selected tags locally before synchronizing with the server and restores them after the new user object comes back down the pipe. One potential issue that should probably be fixed is if a tag is deleted on another client that has it selected, there is no visual feedback showing that a tag is still selected, but there are no tasks shown because a null tag is selected. This is fixed by pressing "clear filters", but null filters should probably be checked eventually
