[webkit-dev] Python on the Tiger build bot

WebKit's gold-standard development system appears to be Leopard.  (I
would guess Snow Leopard, except the SL bots only finally turned green
about two weeks ago.)  Leopard's python is 2.5.1.

I agree that we should target making development as simple as possible
for the common/standard system.  I think WebKit does an excellent job
of this, although we could always do better.

However, for sub-standard systems (like Windows) we require a few
additional install steps (http://webkit.org/building/tools.html).
(Window's cygwin python is 2.5.5.)

1.  I think Python 2.3 is an example of a sub-standard system.

2.  Additionally, Tiger seems mostly ignored by WebKit (note examples
like https://bugs.webkit.org/show_bug.cgi?id=38743).  No one develops
on Tiger to my knowledge (note mjs last night in #webkit noting how he
had no access to a Tiger machine, I certainly don't have access to

I'm happy to add a brief note to the tools.html page noting that
python 2.5 is required and linking to a page.

Our scripts already print:
webkitpy.python24.versioning: [WARNING] WebKit Python scripts do not
support your current Python version (2.4.6).  The minimum supported
version is 2.5.

I'm happy to augment that warning to provide a download URL.

In short, I don't think Tiger (which appears legacy and
maintenance-mode only at this point) should hold hostage our script
development on all platforms.  We should simply update the bot and be
done with things. :)
