- Add cef_create_projects.bat to generate the CEF project files. - Change include paths to be relative to the root CEF directory. - Add patch_build configuration and build.patch to modify the Chromium build system for required CEF dependencies. - Remove old .vcproj and .vsprops files. - Eliminate use of precompiled headers. - Commit generated project files (these will go away in the near future). git-svn-id: https://chromiumembedded.googlecode.com/svn/trunk@50 5089003a-bbd8-11dd-ad1f-f1f9622dbc98
