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 remove this line, it's unneeded given the other changes I'm going to have you make :-)
