highlight section on section edit button mouseover

Ignore-this: 128d5873729a0a00558465b45d5d9f58

Some people seem to have problems to see which section will be edited when
using a section editing button. This patch adds a litle bit JavaScript magic
to highlight the edited section to be, when hovering over a section button.
