Permalinks on Titles

[iwillspeak]

Currently titles have an #id assigned to them to allow linking from within the page. These links can be copied and used to share a deep link to a certain page section. We could do with a few ergonomic improvements however:

• Highlight the target item in the TOC if an ID link is active
• Add # or link icon on hover to the titles to make it more obvious that these can be copied. We could even add js onclick handling to copy them.
