Takes steps to make our PlatformScreen implementation more portable.

Introduces ChromiumBridge as a means for our WebCore port to depend on the embedder indirectly.  This will be extended to support the rest of our port.

WebWidgetImpl and ChromeClientImpl both needed to have their platformWindow getter implemented.  This fixes a regression related to the most recent merge.

Removes the orphaned Language.cpp (see the real one in the platform/chromium directory.

Changed webkit_glue::GetMonitorInfoForWindow to webkit_glue::GetScreenInfo.  This resulted in a varied amount of plumbing changes.  It also pushes the platform specific bits up into the browser where they belong.

ScreenInfo is a struct that is part of the webkit/glue API.
