Break cef.h into multiple headers (issue #142).

- Move wrapper classes from cef_wrapper.h to wrapper/ directory.
- Move C API functions/classes from cef_capi.h to capi/ directory.
- Move global function implementations from cef_context.cc to *_impl.cc files.
- Output auto-generated file paths in cef_paths.gypi.
