[FEATURE] mzTab 1.0

The MzTab publication has been accepted so I think it is kind of urgent to get the current MzTab data model into OpenMS. I also (temporarly) removed code that used pre release versions of the MzTab specification. Converters for our data formats will follow but require some common efforts with mzIdentML/mzQuantML implementation and data models. Syntax validation is done but only basic semantic validation. This is a larger task and will be extended in the future (also relevant to mzIdentML/mzQuantML).
virtual destructor for base class is missing
