Allow arya and other scripts/utilities from arya to be imported.

Fix up a few other things:

* APICPACKAGES updated
* POLUNICONTAINED updated
* Bump arya version to 1.1.0 to indicate pretty significant functionality (importable) included compared to before.
* Add console_script entry_points for arya to run arya.py by simply running 'arya' (without .py).  Did the same for getconfigfromapic and apicxmljson
