Idle Broc - prototype 0.16

Lots of small UI & balance changes but some of the main ones since I made this playable yesterday are:

• Saving has been enabled. Manually done from a button at the top right of your screen.
• Challenges how has a "Claimable" filter. Shows completed but not redeemed challenges.
• Navigator has been given a unique effect.
• Retaliate is no longer percentage based.

Heads up -- while save files will work in the current build (maybe with some quirks) I am not looking to preserve their integrity as I move forward which is why they were disabled in the first place. I will try-- but these are not forever saves-- let alone that the game isn't close to done and only has a few hours of content anyways.

Also, remember that this web build has quirks that the Steam build doesn't have just because I've uploaded it here as a quick and dirty way to share progress.
