Fixes #98

This change adds 'var' declarations for global variables to allow the tests to run in strict mode (see issue #35).
Extra care was taken to ensure the changes do not alter the test behavior, for example when implicit creation of global variables are part of the test.
Note: The change does not fix all strict mode errors due to missing 'var' declarations.
