Fixing issue #115

Added the GitHub link for the project as temporarily homepage link.

There's still an unresolved warning in composer.json:

     php composer.phar validate --no-check-all
    ./composer.json is valid, but with a few warnings
    See http://getcomposer.org/doc/04-schema.md for details on the schema
    No license specified, it is recommended to do so. For closed-source software you may use "proprietary" as license.
