Release of the very first version of newsdlang

newsdlang is a yet another SDLang parser, that is also equipped 
to parse hexadecimal numbers, ISO dates, etc. (XDL - Extendible 
Declarative Language). Currently it's lacking in features, and 
the previously advertised KDL-compatibility might get dropped, 
while other features from that get adapted. Unlike SDLang-d, it 
can store and mostly restore comments, although with potential 
formatting differences.

A lot of features have to be tested, next I'm going to validate 
whether the current features work as I expect them to. Feel free 
to provide me testcases too!
