This means that you can run just a single case from the command line,
for example:
`qa_pcbnew -t DRCCopperSliver/_0`
The case is also automatically printed as context.
This means that when isolating a specific defect in one case,
you can run only that one case, which is useful under debuggers
and also when using slow tools like valgrind.
Not all possibe tests are doing this, but they're easy to do
when needed (i.e. when you want to run just one case)
Recommendation is to avoid using the year nomenclature as this
information is already encoded in the git repo. Avoids needing to
repeatly update.
Also updates AUTHORS.txt from current repo with contributor names
The IO_RELEASER is a thin-wrapper around a std::unique_ptr, but done
this way to allow easier addition of a custom deleter in the future if
something needs to call back into the IO_MGR.
