WebKit needs a rebaselining tool (finally)

This is a very rough approximation.  But it works. :)

I looked at bending rebaseline-chromium-webkit-tests to my will, but that effort failed.

This code could be cleaner.  Some of this code needs to be moved to shared locations.

For now just posting this for others enjoyment.  I will look at cleaning it up for landing later this week.

WebKitTools/Scripts/webkitpy/tool/commands/rebaseline.py:43
 +      help_text = "Foo"
Should have some real text here.

WebKitTools/Scripts/webkitpy/tool/commands/rebaseline.py:76
 +          chosen_name = User.prompt_with_list("Which builder to pull results from:", builder_choices)
self.tool.user for testability.

WebKitTools/Scripts/webkitpy/tool/commands/rebaseline.py:83
 +          (downloaded_file, headers) = urllib.urlretrieve(remote_file)
Does this throw exceptions?  Maybe add a FIXME?

WebKitTools/Scripts/webkitpy/tool/commands/rebaseline.py:84
 +          shutil.move(downloaded_file, local_file)
We should svn add the file in case it's new.

I think we could land it as a first draft if we do those things.  Need iteration, of course.

Ok.  This is a good start.  We'll need to refactor this into some of the lower layers at some point.

WebKitTools/Scripts/webkitpy/tool/commands/rebaseline.py:97
 +          actual_path = test_base + "-actual.txt"
This knowledge probably shouldn't be here.
