Commit Message:
DIRECTOR: LINGO: XOBJ: Scaffolding for Widget

Widget is an XObject used in Alice: An Interactive Museum.
The assumption is that getPro returns the drive letter as
the return value of getPro is assigned to a variable called drv.

Resolves the following errors from: https://bugs.scummvm.org/ticket/13204
- WARNING: BUILDBOT: Uncaught Lingo error: Call to undefined handler 'Widget'. Dropping 1 stack items!
- WARNING: varFetch: global variable drv not defined!
