Menu and Menu Toggle: Create motion designs

[lboehling]

Menu and menu toggle components need micro animations. The goal of this issue is the define the following behaviors:

• [x] Define open/close behavior for menu panel
• [x] Define hover/click animation for menu items
• [x] Define hover/click animation for menu toggle
• [x] Possibly define any validation animations for menu toggle?
