This Fixes #973

improvements to search comment display

for @amol-jore
favor putting styles in the style sheets instead of annotating elements

the part names were gigantic! about 3x the size of the notebook name.
i don't understand why they should be h3.  again, please modify the
existing css classes.  like the sans-serif though, applying that!

applying my previous suggestion to use String.split instead of horrible
substring operations

the icons are cute but going with plain author: comment format

recover better for old comment format and if there is no author or comment

also, continue to tighten up the search results layout
