Configuring C14N for NameID lookup

[Rod Widdowson]

I'd just like to point out these checkins:

The impact of this change is

1) That C14N subflows which do not match format will now not be run (previous they were and returned "nope try again").
2) That we have an obvious place to add the choice of "which formats get which C14N", which is represent 99% of user configuration.

This feels quite natural to me, although we might want to move some of the bean definitions around (for instance putting the definition of SubjectC14NFlow/SAML2/Transient/Condition somewhere more obvious), but I'd just like to check that it fits into the general plan since moving the formats from the C14N bean did feel a little strange.
