Fix Phing packed inside the phar PHP archive

[gedrox@…]

Currently if the Phing classes are packed inside the phar archive it does not work correctly.

There are several problems I have found so far.

1. The build.xml file cannot be found in the cwd scope. The absolute path must be given or the PhingFile class improved;
2. There are problems in the Win32FileSystem class when working with the phar paths, as example " phar://c:\dir\phar.phar\phing\tasks\defaults.properties" (is changed to invalid path "phar:\c:\dir\phar.phar\phing\tasks\defaults.properties" what is not recognized by the system);

I've used the tutorial  http://blog.calevans.com/2009/07/19/lessons-in-phar/ for building the phar package, set a classes/phing folder as the dir to archive, used the bin/phing.php as the stub, copied etc/VERSION.TXT into the classes/phing folder.

The reason of making the phar Phing package is to deliver PHP application installation without having to copy a lot of files and no need to ask client to install the PEAR and Phing on their servers.

This realy would make an excellent feature of Phing to have a working phar file downloadable from this site as well.

would be a nice addition.

Indeed. Phing as phar would seriously boost phing adoption, i guess.

Moving this one back to the TBD queue to allow Victor more time.

I agree. I've added #839 to track that particular part of the request.
