Simple multi line support

[Uight]

Just putting it out there. I think this is one of the best solutions to enable basic multilien support for different definitions and comments. Also supports to some extend multiple definitions per line. I think the only "really" better way would be to switch the parser in its entirety like the milestones/v1.8 branch.

Still think this solution could solve some problems. Basically this parser uses the nextlineprovider to split lines based on the prefixes for definitions. it searches for line termiantions ";" or new lines to split definitions.

Basically for what it is its doing a good job. I also fixed some stuff that was criticized when we talked about this in one issue. The line number when an error occures is now pretty accurate. About the same as the vector candb++ errors which might also be one line off at some points. Missing ";" are not longer fixed as that is not done by candb++ which failes parsing if a required ; is not present.
