SdkManager: support for upgrade to Schema #3.

This changes the way the sdk manager looks for schema upgrades:
- when trying to load an XML, parse the root element and scan
  for our XLMNS. If it parses, get the version number at the end
  and use this directly to try to load using the right schema.
- In turn this allows us to distinguish between an incorrectly
  formatted XML (but using the right schema) versus something
  that is not our XML schema or not an XML at all, and then we
  can produce better errors for the user.
- We also then directly know when the schema version is above
  the known value of the tool and can then create the upgrade
  tools node accordingly.
