Connector release repackaging: Livelink connector.
Connector release repackaging: Livelink connector.

Adds a repackage target to rename the downloads from
connector-foo-${svn.branch} to connector-foo-${version}. This is
intended for repackaging release candidates for release, but it will
work from any branch.

Other changes:

* Removed support for tar archives (only CM, LL, and LN connectors
  support them, and they are about 16% of the downloads) and
  English-only builds.

* Added downloads directory to svn:ignore property.
