[WIP] Clarifies 'Predictions' section, fixes #866

An attempt, anyway. We'll see how it goes. See #866 for more details.

The design is problematic. Although I'm not sure how much I can help with that.

At the very least, the vertical spacing between "Right now" and the future income input should be increased. There is more vertical space between the future income input and "With the new pay, how could your benefits change?" than with "Right now", and the first two are strongly related.

Now that the future income input is not the first entry on the page it should get a stronger label.

In general, the current summary and future predictions aren't well differentiated. Not sure how to fix that as the page is already quite busy. I do like the idea of making the current summary more concise and rendering on every page. Although I'm not sure where I'd put that. Super helpful!

@wacii : Thanks for the feedback! Yeah, this is still a WIP and that was just a step along the way of metamorphosis. It's still not done. I'm working from the top down. I've gotten to the basics of the 'Raise' section. Ignore the graphs part for now and let me know what you think. If you want to see it with a cliff, use the data from row 8 of https://docs.google.com/spreadsheets/d/15LyR9yELAfcngj-c7vMdI630b6DwuuXV-dQEJDvU4gE/edit?usp=sharing.

If you look at where the 'Raise' section is now, that's going to be the raise and, if needed, the summary. The 'charts' section is just going to be a 'long view' and have the two long-term graphs. I think I'm going to play with dropping the table and the bar graph to see how that goes over because I don't really know how to include them anymore.

If you have any more thoughts, on what I've said or what I generate, keep 'em coming!
