Drop Python 2.6 and 3.2

[takluyver]

Dropping support for these older versions simplifies various corners of our code, and paves the way for a single codebase that runs on 2.7 and 3.3 (but that will be a separate PR).

[Carreau]

That looks good.

[bfroehle]

Yay! This all looks great. I'm sure we'll discover more 2.6-isms as we clean up the code, but those can be for later pull requests.

In what way does this drop 3.2 support? Is this about the u""-syntax?

[Carreau]

Yes we'll drop 3.2 because of u'' . This pr "drop" 3.2 support because it deactivate Travis test on 3.2 and remove 3.2 from docs.

As Matthias says: this only removes 3.2 from docs and tests. In a later PR, I'll change things to use the u'' syntax without 2to3, at which point it will stop working on 3.2.

Any objections to me merging this? Does anyone else want to offer an opinion on the irunner bit that Brad brought up?

[takluyver]

I'm planning to merge this later today unless anyone objects.

[bfroehle]

No objection here.

[Carreau]

No objection to break master for me.
Annonce on Ipyton-dev first to warn people still on 2.6 and master (does that exists ?) not to pull ?

[minrk]

Nobody uses Python 2.6 with IPython master - we would have heard about the logging issue if that were the case.

[minrk]

Read through, and looks great to me.

[takluyver]

OK, in it goes.

Hey, with 2.0.0 this PR broke various integrations tests on our platform today. We use RHEL 6 and Scientific Linux 6.5 (IIRC) and apparently there is no 2.7 package available.

As the PR describes, IPython 2.0 does not support Python 2.6. If you are on 2.6, you must stick with IPython 1.x.
