Huge Refactoring of FormatParserStorage and all FormatParser's.

FormatParser is now a template, specialized by enum ParserTypes.
new struct FormatParserTrait is as well a template of same type, containing parser-specific information in static entities.
all FormatParsers are now specializations of this FormatParser.
all Parsers can be accessed in a unified manner, given in the new class FormatParserInterface.
common functions are placed in FormatParser_common.hpp as one cannot partially specialize a function class.
some boost preprocessor magic is used in ParserTypes and FormatParserTraits to define the template specialization or to create the ParserTypes enumeration.

We construct all lookup tables and alikes via boost preprocessor magic from a list of all available parser (enums).
we use the templated getParser() and addParser() functions to serve parsers to the outside. Instances are as usual created only once.
