Fix to reduce spacing in header and splash  elements in psychology

Adjusted h1, and h1.title elements along with placing overrides for chapter h1.title for precalculus to reduce header space between beginning of page and Chapter 1 title.  Also reduced space between splash image and Chapter title per W&N request.  Reduced space a little between figure caption and splash at bottom.  Spacing issue should be good now so custom layout for introduction works.
