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.
Please add this new line of code here: `setup_util.replace_text("php-zend-framework1/nginx.conf", "USR", getpass.getuser())`
