Add breakpad support (issue #1131).
- General usage instructions are available at https://sites.google.com/a/chromium.org/dev/developers/testing/webkit-layout-tests/using-breakpad-with-content-shell.
- Mac: Generate "Chromium Embedded Framework.framework" using a new cef_framework target (the libcef target is now only used on Windows and Linux). Rename "Libraries/libcef.dylib" to "Chromium Embedded Framework". Distribute Release and Debug builds of the "Chromium Embedded Framework.framework" folder as part of the binary distribution.
- Mac: Fix the Xcode target compiler setting for the binary distribution so that it no longer needs to be set manually.
