Refactor of draw.py (#150)

* Major refactor of draw.py
* Also addresses Issue #70, Issue #85, Issue #120, partial to Issue #6
* Make the label information more available so it can be picked up easier by the website frontend
* Add Avery Presta 94211 labels, label names
* Add tab-height to make easier calculations
* height is now the full height of the label.  tab-height is the portion used for the tab.
   (By doing this, adding labels is more intuitive and requires fewer calculations.)
* Fix for issue #239 The fix changes this to now include the original expansion in this case.  So now this results in the original expansion expansion being printed with the upgrade expansion cards included as well.
