Make table cells fully clickable

See #1273 for the full
explaination.

This needs some hacks in CSS for firefox & chromium (or the other way around is also
possible) given that most major browsers are now chromium based it makes
sense to use that as default.

The selector `td:not(.testcase-results)` is to make sure that we are reasonable
specific to be applied on the tables, it does actually target everything
because the testcase-results class doesn't have anchors in the cells.

All the anchor tags are now stretched to us the full space inside the
TD.

Based partly on logic in:

This has as disadvantage that we need the extra classes to keep the rounded buttons (a + border) aligned but as we only have this once it should be accepted.
