Fix some issues with typing generation when xs types are used

[zanemcca]

• Array types that contain a namespace are mangled by the typing generator. This is fixed by explicitly keeping all array setup text prior to the namespace.
• An xsd:decimal may have some typeData included which caused the typeData to be interpreted as a set of allowed values. The fix included catches all number types and makes sure they map to number

@TimLuq Could I get some eyes on this fix?

@TimLuq I would also appreciate to get this fix in. Just found out that I have type "integer" in my generated schema.
