Refactor org.exolab.castor.builder.types package

I finished almost all code formating work and refactoring of class hierarchy. Still improvment of setFacets() and validationCode() methods are missing. Having said that I recoginized and fixed a valueable number of small issues at the refactored classes.

I also need to mentioned that still some XML schema types are not supported. The missing ones are:

• token
• Name
• language
• ENTITY
• ENTITIES
• NOTATION

After this task has been finished I think we should also separate IDREFS and NMTOKENS from our global COLLECTION type (XSList) to omit looking into the collections component type at various areas.

It need to be noted that I changed one contract during refactoring, values like maxExclusive or fixed are not validated during source generation as their value range should be valid if the xsd is valid.

In addition to the observation of none supported types there are still 4 supported types that do not support all factes or no facets at all.

• base64Binary
• heyBinary
• dateTime (as already mentioned by eddie)
• IDREF

All other types now support all facets which they didn't do before the refactoring.

Another bug that I fixed was at xsd:integer, xsd:positiveInteger, xsd:negaitiveInteger, xsd:nonPositiveInteger and xsd:nonNegativeInteger. While they used Long class we called Long.intValue() instead of Long.longValue() at conversion to a primitive value.

Final patch.

At the list of types where facet support are missing and no validation code gets generated i missed xsd:anyURI.
