Make bug statuses in index.html files quotes

Instead of code blocks the bug / (mis)features statuses are quoted
rather than in a code block. In the case that there is more than one a
line break was added at the end of all but the last one.

A bug status was renamed to be slightly more correct (maybe more than
one was renamed for the same purpose but at least one was).

The bug statuses in the quotes are now bold to let them stand out
better.
