[WSS-180] - Backported fix for "Support symmetric signature/encryption via configuration" to 1_5_x-fixes
- This involved changing how WSHandler gets Crypto instances...it doesn't throw an exception now if there is no crypto instance
[WSS-203] - Moved to JSR-105 API's for XML digital signature creation
- Processing move to follow.
- All the tests are passing...there are a few hacks in there though that need to be ironed out.
