Rename Suggestinator to Strategizer

[mariakleiner]

or Strateginator? :)
This is to avoid confusion between "suggestions" that currently mean suggested plans and "suggestions" that are currently named "descriptions". After this is done, description-generator should be renamed to suggestions-generator (or suggestinator?)

Shane, Doug, please, let me know when is a good time to do the renaming to not interfere with any of your work in progress, thanks!

I was landing the strategizer with the new name, then planning to remove the old suggestinator when it was ready to switch over, but I see how that might get in your way. But it's fine to just rename suggestinator.js to old-suggestinator.js or something. I don't think we need to rename any of the classes since they will just be removed later.

oops, i seem to have totally missed this - fea7b79
i guess, i just hold off renaming descriptions to suggestions until the new strategizer replaces the old suggestinator. thanks.
