Fixes #192 - integer problem on string value
Upgrade composer PHP version to 5.4.0
Add phpDocumentor configuration

This is the bare essentials for phpDocumentor.

Simply run `phpdoc` from the `/docs/` folder.

To customize, copy the `/docs/phpdoc.dist.xml` to `/docs/phpdoc.xml` and make your desired changes, then run `phpdoc` to regenerate. The `phpdoc.xml` file is your custom file and will be ignored by git.
Iterator was duplicating first result due to extra data seek
Iterator was duplicating first result due to extra data seek. This also causes the last resultset to be lost in iterator mode.
Iterator requires access to additional properties
Since the iterator may throw an error, it needs to have access to both $this->link and $db->dieOnErrors
Also $zp_real was incorrectly used where $this->dieOnErrors was required
Rewritten test due to signature change.

Poor scoping in action class means $zcRequest is not available in templates

See Issue #200

tplHeader directly addresses the $zcRequest variable when multiple languages are installed.
However on the home page which is served via an Action Class, $zcRequest is not in the global scope, as templates are rendered using a method of the ActionAdminBase class.

Need to add a template variable to pass in the current cmd param so this can be rendered correctly in the tplHeader template.
