Automatically add XTS and TXBridge handlers to Web Services that use JTA annotations

Currently the developer needs to specify the XTS and Bridge handlers on the Web Service that wishes inflow a WS-AT transaction. This is cumbersome and error prone.

It is quite easy to infer if the user needs these handlers by checking to see if the Web Service uses @Transactional or @TransactionAtttibute and by looking for a WS-AT transaction context on the inbound message.

The same can also be done for the Compensations API, by looking for @Compensatable annotations on the Web Service. In which case, only the XTS handler should be added as no bridging is required.
