libcef: Update due to underlying chromium changes.

- Add the printing project and delete duplicated files from the CEF printing directory.
- Add media-related projects and support for <video> and <image> tags.
- Use WebKit::WebHTTPBody instead of net::UploadData for web requests.
- Numerous changes due to continued cleanup of webkit/glue and webkit/api/public.
- Use a separate BrowserWebViewDelegate instance for popup windows.

libcef:
- Add support for printing to file.
- Use WebFrame::GetFullPageHtml() instead of webkit_glue::GetDocumentString().
- Parse extra header values in RequestProxy for passing to CefHandler::HandleBeforeResourceLoad().
- Add urlmon.lib dependency in libcef.vsprops.

tools:
- Add the patch application tool (patcher.py).

patch:
- New project for applying required patches to the Chromium source tree (issue #47).
- Add webkit_glue.patch for http://codereview.chromium.org/160004

cefclient:
- Add new test for submitting and handling requests.
- Don't change navigation button state for popup windows.
- Fix problem on Vista where the string returned by EM_GETLINE is not NULL-terminated.
