Scaffold User Game Library Page

[dgautsch]

Eventually when a user has created an account and linked their steam profile. There should be a page for them to view their games. Clicking the game should show the ROI stats.

This ticket's goal is to scaffold out the page.

This ticket is complete when:

• Create a Vue route component to house the user game library
• The routes should be updated to include the new page. The requiresAuth flag should be set to true.
• The page should use the element UI library to add a title that says "Game Library", make sure the route meta is updated too
