  ability to set Id attributes

* Remove redundant code from SignedInfo that was preventing the 
  library from loading signatures it did not have an algorithm hard
  wired for
* Fix bug in envelope transform when input nodeset is a document
  fragment rather than the entire document and the canonicalisation
  uses a namespace that was not defined directly in the fragment

  potentially causing an exception when an XPath expression was loaded
  reported by Ralf "Sabo" Saborowski.

* Performance improvements in canonicalisation
* Implemented algorithm handlers for the digital signature classes, 
  to provide algorithm extensibility

  references are interlocking.
* Provide some stability if the Apache keystore is corrupted under Windows.
