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 replace the last parameter (`"root " + home + "/FrameworkBenchmarks"`) with `"root " + args.fwroot` to reflect changes introduced in #915. Also, please remove the following lines as they are unneeded here: 
```
from os.path import expanduser

home = expanduser("~")
```
