Improve tooltip accessibility (#1954)

Browse Source 
There has been the requirement to improve accessibility for our tooltips by allowing tooltips to be closed via the escape key as well as allowing users to hover over the tooltip text. These combined requirements were not possible with the previous implementation that used a bulma-tooltip extension. That meant we had to implement the full tooltip html and css from scratch. A declared goal was to keep the new implementation as close to the previous look-and-feel as possible. The redundant dependency has been removed in the process.

This is the fixed re-commit of #1938 (Commit 67bd96ea81)
