Updated screenshots for visual tours needed

[Ian Clatworthy]

It would be nice if the visual tours were updated to show the new
Explorer 1.0 and QBzr 0.18 screenshots. IIRC for the Bazaar 2.0 release,
I did the Windows images and community folk pitched in with screenshots
for GNOME, KDE and OS X. This time around, I was hoping for a similar
amount of assistance, if not more. :-) Perhaps the Windows images could
be refreshed with Windows 7 versions?

If you can help sometime over the next week in updating the images,
please do so. The master branch to submit merge proposals against is
lp:bzr-explorer-website.

Thanks,
Ian C.
