The function was wrapped as a named function expression (function foo(){})
which scopes the name 'foo' only to the function body, not the outer scope.
_initApp called setTimeout(_checkWebappUpdate, 6000) causing:
ReferenceError: _checkWebappUpdate is not defined
Fix: remove the (...) wrapper so it becomes a regular function declaration
visible to the entire module scope.
Fixes #7
