Move to GYP-based project file generation (issue #48).

- 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).
