Oxygen-Molecule KDE & GTK+ unified theme

Oxygen-Molecule is a theme for GTK+ applications to provide a uniform look when used under the KDE 4.3 desktop environment. It was originally based on the kde4.2-oxygen (modified) 0.3 GTK theme by Dennis Schmitz (which was itself based on work originally by Kim Kahns) (url: http://www.gnome-look.org/content/show.php/kde4.2-oxygen+(modified)?content=99926)

On top of the original theme, I have made the following changes:
- changed colors to match default KDE 4.3 color scheme, including hue adjustment of all pixmaps
- reworked most of the pixmaps and changed measurements for improved visual appearance
- created new spinner buttons, since the original spinners often looked mismatched with the surrounding pixmaps
- linked the GTK theme with the Oxygen icon set (thank you Craig Drummond for showing me how to do this).

Additional documentation and installation instructions are included in the download.

2.2:
- Removed theme's dependency on the Murrine engine.
- Made check and radio boxes smaller for web pages rendered in Firefox. (Fix committed by Craig Drummond.)
- Fixed appearance of selected menubar items. (Fix committed by Craig Drummond.)
- Improved the appearance of check and radio boxes within menus.
- Fixed tree view text color

2.1:
- Redesigned scrollbars with new shading effect.

2.0:
- Updated the theme to be compatible with the new KDE 4.3 tabs.
- Oxygen-molecule now links directly to the existing oxygen icons, so the OxygenRefit icons are no longer needed.
- Updated the selection box to match KDE's.
- Set the scrollbar width to 17 pixels to match the new KDE default.
- Tweaked the menubar gradient to match the titlebar in a higher percentage of cases (it's not possible to get it fully accurate for every window width).
- Added a vertical window background gradient, which means that the window background will better match the frame when used with the Oxygen/Ozone window decoration. Due to a limitation in the pixbuf engine, this won't always be perfect, especially for windows that are small vertically.
- Fixed the grey tooltips.
- Greatly improved the appearance of progress bars and scrollbar arrows.
- Made the buttons smaller.

1.2:
- Provided solid colorizations for buttons, check boxes and radio buttons so they would not appear transparent in Firefox.
- Made menu item highlight slightly thinner to more closely match KDE apps.
- Reconfigured many icons as symbolic links to the oxygen icon set. This cuts down on disk space use considerably.

1.1:
- Redesigned check boxes and radio buttons to have a glowing mouse-over.
- Check boxes and radio buttons have improved spacing, especially on web pages in Firefox.
- The default button in a dialog now appears as it does in KDE apps, with a dark blue outline
- Redesigned sliders and gave them a mouse-over effect.
- Made large improvements to the appearance of frames. Previously, they looked very buggy.
- Buttons are now a little thinner, so they look more like they do in KDE apps.
