[webkit-dev] minimum python version to support

[Marc-Antoine Ruel]

FYI, Chromium folks on Windows will be on python 2.6 real soon(tm).
The CL to bug them to upgrade should be committed within the next few
minutes.

[Thread hijack]

If you're not a Chromium-Webkit committer running on Windows, please
ignore the rest of this email.

Otherwise, please "del depot_tools\python.bat" and run "gclient".

Thanks,

M-A
