screen/integrate changes from Martin Mrose

[FelixSchwarz]

There is a soapbox fork by Martin Mrose which contains several interesting changes. We should screen the repository and integrate whatever commits look sensible.

Licensing note: The code was forked after the OSL relicensing but the author agreed in private email to license all changes.

I allow you to use my changes under BSD.

Made appendix of input and output message customizable

• commit f1559ca
• seems to be too specialized + unclear use case: I'd rather add hooks for WSDL generation
• workaround available: with SOAPDispatcher users can always choose to serve their own WSDLs instead of having to rely on soapfish

Ability to return custom SOAP faults (fault details)

• commit f1559ca
• implementation as-is too hacky as the current soapfish code allows a better/more complete implementation
• tracked in ability to specify details for SOAP faults #37

Include faults in WSDL

• commit f1559ca (method.faults), cf580e5, e1584b4, fc586df, 8b04cec, fce1fb2
• seems to be a reasonable change
• without tests I'm not sure that this is correctly implemented so not merging right away

"fixed validation"

• commit 52df958
• fixed independently

add support for union types

• commits 321d896, 40535bf
• needs cleanups and tests but otherwise legitimate
• tracked in add support for union types #38

Added choice support for complex types

• commit 3f334f5
• needs verification and tests but otherwise legitimate
• tracked in support Choice indicator in generated XSD #39

Added previously ignored elementFormDefault

• 59f2c35, 4606744
• fixed independently in a11415e

seems like all interesting changes are now properly tracked in separate tickets or already implemented.
