New openssl package solves permissions problems with Linux build.

The original Linux openssl tarball includes libcrypto.so and libssl.so files
with r-xr-xr-x permissions: not even the owning user can modify them. This
causes problems when the Release build tries to 'strip' the viewer and all
associated libraries. Newer openssl tarball fixes permission problems.
The newer openssl package also updates from 0.9.8 to 1.0.0, so have to fix
version numbers in Copy3rdPartyLibs.cmake and viewer_manifest.py too. :-P
Presumably the only reason this hasn't been causing trouble with TC builds is
that the link has been picking up system libraries instead of the ones from
the openssl package.
