Pass the results of the InternalLaTeXAuxAction back up the call chain

in teh various tex builders. This allows the user to interrupt the build
which was not working before.
It also allows configuration tests to work since now they can tell if
there was failure in a test.
The result from the internal MakeIndexAction and BibtexAction are
checked as well and control returned if there was an error in one
of those. This is to avoid repeatedly running commands until we
hit the retry limit.

I added no test for this simce I am unsure how to test for user
interrupts. Also unclear how to test for how many times the internal
actions were run during a test to see if it returns on teh first error!
