Version update for Transcrypt: 3.9.3

[JennaSys]

Since becoming custodian of the Transcrypt project, I've only made minor changes to the codebase up to this point. With the upcoming v3.9.3 update, that is no longer the case. Depending on how it is being used, there may be some breaking changes in v3.9.3.

Based on reported issues, the map, min, max, copy, deepcopy, sort, and sorted functions have all been refactored to be more closely aligned with CPython. If you were previously relying on a Transcrypted behavior for these functions that was not aligned with CPython, they may not work the same way now. On the plus side, some annoying workarounds for non-CPython behavior or missing features may no longer be necessary for these particular functions.

If you wish to test out the changes for yourself before it is released to PyPI, you can install it directly from the master branch with:

pip install git+https://github.com/TranscryptOrg/Transcrypt.git

All of the transcrypt autotests are currently passing, but if you run into any new problems with it, please let me know. If I don't hear of any major issues, I should get it pushed out in the next few weeks once I've had a chance to better test it myself.

Edit 24-07-17: dev_3.9.3 branch has been merged to master branch.
