Adds Bootstrap to PHPUnit Configs

Needed to add `vendor/autoload.php` as bootstrap in phpunit.xml.dist so
NoCrupht classes can be autoloaded for tests. For now, this works, but in
the future, if we ever need to do more than setting up autoloading,
`vendor/autoload.php` will need to required within a general bootstrap
file, and that file will be referenced in the phpunit.xml.dist as the
bootstrap.
Adds Router Tests

Adds tests for Router class. Testing a few routes with a simple closure
against a few urls to ensure the Router passes the correct values into the
closure. Also tests for "No Route Found" exception as well.
