Icon Refactor

Icons can always be refined! After completing the first set of our menu icons a couple years back, I've wanted to revisit and improve upon them. This is just a quick snippet of the new set. Some of the improvements are subtle, while others are very apparent. Overall the new set benefits from a cleaner, more balanced template, a more saturated and harmonious color palette, and a new "hollow" variant that is useful in empty states and patterns. I'll show off more progress soon!
