Improved the connect function

The current `TwitterComponent->connect()` function establishes the URL
very crudely, breaking the callback function for CakePHP apps running
in sub-folders.

This change simply replaces the manual URL creation with a call to
CakePHP's Router function, and asks for an absolute URL.
