Added the bigtable css class to all testresults tables that were missing it.

This reverts commit b354bca0.

Unfortunately, Afrikaaans is the default selection of the language, and
some people apparently contributed translations without selecting the
proper locale. I see some Hebrew text in here, which was easier to
distinguish because it uses an entirely different character set.

But I have to assume other locales are mixed in here as well.

I'll remove the default language from the translation assistance plugin.
But in the mean time, we don't have anyone who's capable of reviewing
this, so I'm forced to roll back.

Now lists error details, stack trace, stderr and stdout provided its content is
not empty.

This adds an extension point, TestNameTransformer, which is called to transform JUnit test case names.
This is useful for JVM languages like scala which are more flexible than java with identifier naming.
Scala, for example, allows you to write test names between back ticks, and then encodes the name using valid java identifiers.
This extension point would allow a plugin to transform those names back in to readable names when they are displayed on the test result page.

Observations:

- When marked inside, moving the mouse to <A> and clicking the context menu becomes easier,
  because you can move the mouse toward the hot spot area and it'll activate.
  Otherwise you have to move the mouse over to <A>, then move the mouse on the side, click it,
  then click the menu, which adds cognitive stress.

- Marking model link as inside creates an empty space to the right of <A>, which looks
  odd if hyperlinks appear inline or if some other text follows it.

Given that, my guiding principle for this change is:

- any model link that is the last child of a block element gets marked as inside
- I've adjust a few text to get rid of the single-letter training text after a model link,
  like "(#3)" to "- #3"
- If another inline element follows a model link, leave it as is.
  This does create an ugly overlap.
