Message:

developer.wordpress.org: Set handbook-related flags and data once via query variables rather than assuming (or always checking for) the presence of handbook plugin template tags.

Specifically sets 'is_handbook', 'current_handbook', 'current_handbook_home_url', 'current_handbook_name'.

Props keesiemeijer.
Fixes #1671.
