Add Zend framework 1

This PR adds a quick version of the benchmarks for Zend Framework 1.

This is modelled after the ZF 2.0 version of the benchmarks https://github.com/TechEmpower/FrameworkBenchmarks/pull/218 and is mostly created the way the zf-tool creates a sample project.

Please review.
@methane nginx actually forks itself into the user specified in his `nginx.conf`, which is why the sudo is being used. We could definitely do this better but it does work :)

@gerardroche please change `"sudo /usr/local/nginx/sbin/nginx -c " + home + "/FrameworkBenchmarks/php-zend-framework1/deploy/nginx.conf"` to `"sudo /usr/local/nginx/sbin/nginx -c $TROOT/deploy/nginx.conf"`
