Genre console

[donleistman]

• BrowseProducts, AllProducts, and SidebarFilter have been refactored to move all shared state into the BrowseProducts container component
• Two sort functions added to the Utils folder
  • Genres and Consoles (as 'Systems' to avoid collision with the 'console' global) added to Models, Routes and seed file
• Genres and Systems added to store, along with state for the genre and system selected in sidebar dropdown menus
• Sidebar now allows users to filter by Genre and Console, search by text, and order by price or title, with all these filters accumulating on top of each other.
