New designs call for a streamlined New Portfolio page, with far fewer input options. This commit refactors that page according to those designs. Some of the route functions in this commit refer to a "step 1" of creating a new Portfolio. Though there is no "step 2" right now, the designs call for a multistep flow for Portfolio creation process, so this commit sets the stage for that.
Generic single-database configuration.
