[FEATURE] Add ant build script

Burried inside my repo, there's this ant build-file.

It follows the general [Jenkins PHP Toolset](http://jenkins-php.org/) in terms of Features,
but is optimized for using it with the TeamCity build server.

For using it, you have to adjust the properties file with the current values.

A default build _should_ produce various metrics (phpcs, phploc, phpcpd, lint.....) and a PHP CodeBrowser with annotations to problems (like: There are current 22 occurences of c&p).

This may be useful for the new travis builds. Ideas for extending it:
* RSYNC'ing of build artifacts to the FT3 server for general public access (like the discussed docs site)
