Selectable activity views

[johan-bjareholt]

Depends on #189
Fixes #79

This makes it possible to select any of the current visualizations in the "Summary" view so it becomes more of a "Favorites" view. You simply press the gear icon in the bottom right and select the type of visualization you want.

TODO:

• Save selection in localstorage
• Make the sunburst view not mess up alignment
• Make views not selectable if they are not available (browser, editor, etc)
• Split up visualization components

Really nice, very similar to what I had in mind for #79 (something Zenobase-like). I have some ideas for how to improve this further (I think the cog-dropdowns look a bit messy when everywhere), but I'll do that myself in another PR.

Yeah, they're not perfect but they're a good start and easy to implement.
I couldn't come up with a better way right now, but I'm sure there are better solutions.
It's also currently just a simple dropdown list, in the future it would be cool if we could have more advanced customization, maybe getting a modal like the event editor where you can customize things a bit more.

This solution in the grand scheme of things is definitely not perfect, but it's a good starting point to make it possible for users to have a custom dashboard.
