Linux UI theming:

- Improve appearance of menus by setting background to white (matching windows and fitting better with the overall appearance).
- Disable user theming of native widgets: since our widgets are a hodge-podge of native and custom-drawn, there's no way we can support user theming. Eventually users will be able to choose a theme for chromium; until then make everything look like chrome.
