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.
Depending on how strongly typed the language is (php... so who knows) you might have to do some other stuff here as well. Our validation also sends some checks like passing `?queries=foo`; this should also have a single query run.
