Fix Router Redirects

[adamseth2]

Current Behavior

The current router does not change the URL, which causes issues. When you refresh the page, it goes back to the home screen regardless of what tab you are actually in.

How to Implement

In main.ts, look at the vue documentation to figure out how to fix the router. Might have to edit Navbar.vue on how it determines how it greys out the navbar's tab as a result.

Test

This feature is successfully implemented if it does the following below:

1. Refreshing the page results in staying in the tab you were currently in
2. Clicking on a tab should result in the navbar's tab being greyed, and refreshing the page should still be greyed.
3. Clicking on a tab should not make the page entirely reload the page (Basically, allows instant change of tabs)
