Oracle: support AllSets.json.zip; Fix #624

Browse source 
Imported unzip methods from OSDaB-Zip project;
Adds a soft dependency on zlib to oracle; if lib if not found, oracle
will continue to compile and work but without zip support.

- [protobuf](http://code.google.com/p/protobuf/)
- [CMake](http://www.cmake.org/)
Oracle can optionally use zlib to load zipped files:
- [zlib](http://www.zlib.net/)
The server requires an additional dependency when compiled under Qt4:
- [libgcrypt](http://www.gnu.org/software/libgcrypt/)
