fix setup.py errors so install and sdist work correctly

* LIBDEST and LIBPYTHON variables seem to exist on different platforms. Check both?
* Fix error in version number making of setup.py (%d when value is string), but superceeded by next change.
* Change version to single string following PEP-0440
* Bump micro version for new packaging. Would be 1.9c, but now 1.9.3.
* Move version info into a __version_info__.py file so it can be imported independently of gerbmerge.gerbmerge. This allows dependency resolution.
* Add requirement for simpleparse so it is installed automatically.
* Add a __main__ for use with `python -m`. This makes it easy to use from a pip installation.
