composer support and 5.3 namespacing
Namespaced everything and ensure phpunit runs through composer
All tests passing, moved phpunit.xml to a .dist
Remove test/config.php.template, use phpunit.xml to set values

Using this in a local phpunit.xml is a better approach:
```xml
<phpunit>
	<php>
		<const name="TEST_ACCOUNT_KEY" value="...."/>
		<const name="TEST_ACCOUNT_SECRET" value="...."/>
	</php>
</phpunit>
```
