Active Challenges View and Update to Main Nav

[elisemarika]

Job to be Done When looking for Challenges to claim, I want to have a view of every Challenge that's active instead of being forced to navigate to a Marketplace first, so that I can save time and easily see what's available for me to work on and earn.

3/1 dev sync consensus is that this type of Challenges view would be easy to build, just a question around UX

@bcinman #443 won't be ready for dev next week, and this is higher priority than #362 ..think you can switch to this after we're done with refactoring?

@A4x1 @bcinman also incorporating styling on Challenges for users to quickly know what they claimed would be helpful as part of this too (similar to what we introduced for Submissions - "you + n others")

3/15 decision - with deprecation of Brainstorm, will update the main nav to be: Showcase, Challenges, Marketplaces
