1.0.0

Creates first stable fully tested release of the Acquia PHP SDK.

All API implementing methods are unit testable with PHPUnit and provide a response class for simple type hinting when using the SDK with other projects.

The implementation of the SDK has been changed since the initial development release to allow for injection and the README should be consulted for further details.

Big thanks to @rujiali for the lion's share of refactoring and creation of a properly unit testable codebase.
