Adding version information to DroidDoc. Rather than pulling the version from

@since tags in the code, it's pulled from the API XML files also used by
apicheck.

The code now reads the apicheck XML, and applies it's versions to the DroidDoc
class models. The models output the version to HDF, and that's picked up by
the CS templates.

The clearsilver templates will be changed to be pretty in a follow up change.
