Hbc::SubversionDownloadStrategy#compress

TODO/UPDATE: the tar approach explained below is fragile
against challenges such as case-sensitive filesystems,
and must be re-implemented.

Seems nutty: we "download" the contents into a tape archive.
Why?
* A single file is tractable to the rest of the Cask toolchain,
* An alternative would be to create a Directory container type.
  However, some type of file-serialization trick would still be
  needed in order to enable calculating a single checksum over
  a directory.  So, in that alternative implementation, the
  special cases would propagate outside this class, including
  the use of tar or equivalent.
* SubversionDownloadStrategy.cached_location is not versioned
* tarball_path provides a needed return value for our overridden
  fetch method.
* We can also take this private opportunity to strip files from
  the download which are protocol-specific.
