Correct composer.json.

'type' and 'repositories' are unnecessary. 'autoload'
should use class map instead of PSR-0. The library
doesn't follow PSR-0, instead you will want a class map.

Instead of 'version', please use tags. Using tags allows
us to actually use this repo with ease, and removes
human-error factor. Tags bring working version
constraints and dist support (which removes git
dependency).
Composer no longer accepts uppercase names.

The package should be re-submitted to Packagist
with a name that follows the naming convention. When
the package was first submitted, there wasn't validation
present at Packagist. Nonetheless, the name doesn't
follow the convention.

Packagist must follow format of either:
* lower-cased/with-dashes
* lower_cased/with_underscores

After changing the name the package can be resent to
Packagist.
