Speedup for image placeholder record creation.

This gets called in a loop - once for each section retrieved,
and it was unnecessarily saving each time inside the loop,
instead of once afterwards. Much faster this way!

Much faster table of contents.

Fixes issue with toc jumpiness near bottom of articles.

Fix for web view scroll delay.

Much better handling of TOC show/hide swipe.

Now angle and speed of swipe is tunable. Works better with
html tables which have overflow x scrolling also.

Fixes for mutate-while-iterating bugs.
