Fixes and non-critical testing for Python 3.10-dev

[avylove]

Travis added support for testing early releases of Python 3.10. Everything works except the version test in __init__.py, which needs to use integers instead of strings in order to support comparison of two digit version elements.

The main reason for a release is to support downstream testing of 3.10, which is how I found the bug. What do they say about testing? Early and often.

I agree, that code can probably be deleted. There are no downloads for 3.2 and even very few for 3.3. Here are the stats for the last month.

python_version	download_count
3.6	95,327
2.7	73,348
3.7	52,873
3.8	52,243
3.5	12,527
3.4	1,111
3.9	90
3.3	48
2.6	8
3.10	3
Total	287,578

Actually, if we do that, we should probably drop 3.2 from the supported versions, but while the net effect is probably nil, that shouldn't be done in a bug release. So I'm thinking just fix it for now and drop 3.2 the next time there's a feature release.

Sorry for the extra commits in master. I think github had a hiccup. I did a squash and merge, but it told me it failed. Then I saw it did a merge without the squash
