Fix linting issues

Fix for issue #39 

Find instruction was throwing the following error message on windows
machine "find: invalid predicate `-wholename'". To test on unix-like.

Removed unused vars in tests. Added conjure function global instruction
in objectInit and arrayInit.
This shouldn't be necessary if jshint is aware of the fact that we're using a module pattern. The `conjure` function isn't a global. It's local to the module.
