Remove embedded php cgi binaries

[belgattitude]

Removal of obsolete php-cgi binaries in the WEB-INF/cgi directory. They're too outdated and newer versions can be easily installed on any platform.

For example on ubuntu

$sudo apt-get install php-cgi

This solve issues with the .war bundle being too big.

For deployment, please ensure your web.xml use your system php-cgi binary. Check for <param-name>prefer_system_php_exec</param-name> in context-param. See an example below:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">

<web-app>
    <!-- support for JEE cluster, remove this line if you want to put non-serializable objects into the java_session() -->
    <distributable/>

    <context-param>

        <param-name>prefer_system_php_exec</param-name>
        <param-value>On</param-value>

        <param-name>php_exec</param-name>
        <param-value>/usr/bin/php-cgi</param-value>

    </context-param>
