Title: Fix issue #34

Issue #34 points out that Windows 32-bit will throw a `KeyError` exception when trying to do `os.environ['ProgramFiles(x86)']`.

This patch changes the behavior so that if that environment variable is missing an empty string will be returned.

The empty string will be ignored in the `os.path.exists()` check later in `tshark.py`.
