Don't import past.translation by default when importing past

[chadrik]

There are two reasons to make this change:

• It is a waste of time to import all of the lib2to3 package just to do e.g. from past import unicode
• More importantly, the import of lib2to3 does not work on certain python distributions, including zipped python installations. See issue Import from past causes traceback #209 on this repo and this core python issue.

This is a backward incompatible change due to the change of location for autotranslate, but I think it's the right thing to do for the start of the version 18.x line.

Just wanted to throw some additional weight behind this PR. This PR appears to fix python-future for embedded/zipped installations and that's a pretty big deal!

To frame this in my own context, this issue effects users in the domain of visual effects because most DCC applications -- Autodesk Maya, SideFX Houdini, and The Foundry Nuke -- embed a zipped version of python. Having this implemented can really help users like me in the coming year as the VFX industry prepares for a push to Python 3 in 2020. Obviously dropping python-future is an option, but, it's such a convenient library!

Cheers!

Yep, I'm in VFX as well. VFX/animation is a bit late to this party, but we need our pythons futurized too!

Unfortunately, if it's a dependency of a third-party library, like it is in our case, we can't drop it.

Thanks!
