Provide correct framework name string for Mac buildbot package.
Added support for intercepting popup urls
Updated key event to have all the valid parts
Added win32 windows hook to get raw key events
Properly copy subdirectories in the CEF_BIN_PATH, e.g. CEF.framework.

The Mac buildbot package for CEF 3 unpacks to a framework structured as a
CEF_BIN_PATH/Chromium Embedded Framework.framework directory containing a
Chromium Embedded Framework binary plus Libraries and Resources subdirs. But
the foreach loop in CMakeLists.txt copied every CEF_BIN_PATH entry as a file,
producing a zero-length file Chromium Embedded Framework.framework in the
target directory. This benefits no one.

Detect the presence of a subdirectory and use the appropriate copy command.
Use correct Mac string library name: libcef_desura.dylib.
