[Feature] phar package distribution for basic package and addons

[dkreuer]

As many code quality tools are already available via https://phar.io/ as scoped phar archives (https://github.com/humbug/php-scoper) Captain Hook might as well provide them for easy install and isolation from the using project.

Is that sth. useful?

Version 5 of the Cap'n will support a PHAR file installation
