Android SDK Search troch Sebastian

1. Adds an 'ad' command to the Awesome Bar. For example, typing 'ad ViewGro' will bring up a list of all class names in the Android SDK matching 'ViewGro'—selecting a list item navigates to the relevant Android SDK Reference URL on developer.android.com.

2. Adds a '(view source)' link next to the SDK class name for class reference pages on developer.android.com. Clicking this link navigates to the relevant Google Code Search results from android.git.kernel.org.
