- Delete include/cef_runnable.h (issue #1336). - Build the cef_unittests target using all Chromium headers. Add a USING_CHROMIUM_INCLUDES define and libcef_dll_wrapper_unittests target to support this. This change avoids compile errors due to the divergence of CEF and Chromium base/ header implementations. The libcef_dll_wrapper sources must now compile successfully with both CEF and Chromium base/ headers (issue #1632). - The onbeforeunload message specified via JavaScript is no longer passed to the client (see http://crbug.com/587940).
