Provide "Tabris" object for compatibility with clients
Provide "Tabris" object for compatibility with clients

In commit e49c1c23, the global object "Tabris" has been renamed to
"tabris" (lowercase). This change broke the native clients that still
access Tabris._start and Tabris._notify.

Provide a compatibility object "Tabris" until the clients are adjusted.
