Brainstorm idea of parser states to support tests
Add rough support for testing status indicators

"**passed**" line is parsed and listed as neutral issue task.
"...failed testing" line parsed and listed as error issue task.
"(failed-as-expected)" parsed and added as task, but see inline TODO.
Add file names processing to enable the cool QtC feature of automagical
file lookup by name only within the whole project files.

Not perfect, but fairly usable implementation of #3 enhancement.
Merge branch 'parse-tests'
