Remove 3rd party libs from our repository and define the dependencies in composer.json-dist.

Also remove the ancient utf8 lib and replace it with 'Patchwork UTF-8 for PHP'.

For direct git checkouts, copy composer.json-dist into composer.json and run
`php composer.phar install` to install the dependencies.

- * Crypt_GPG is a package to use GPG from PHP
- *
- * This package provides an object oriented interface to GNU Privacy
- * Guard (GPG). It requires the GPG executable to be on the system.
- *
- * Though GPG can support symmetric-key cryptography, this package is intended
- * only to facilitate public-key cryptography.
- *
- * This file contains an abstract implementation of a user of the
- * {@link Crypt_GPG_Engine} class.

- * PHP version 5
