The default en-US locale pak file fails to load on Mac

[GoogleCodeExporter]

There is an error: "locale.file_path empty". The Resources/en-US.lproj/ 
directory is missing. On Windows and Linux there is an "en-US.pak" file.

The solution was to set the --locale_pak=Resources/en.lproj/locale.pak flag.

Now after looking at the CEF sources I see that it should be fixed by setting 
the --lang=en flag or using ApplicationSettings#locale_(string) option.

I am wondering if this error might have something to do with the fact that 
we're not using the directory structures like the one found in cefclient.app. 
CEF libraries are in the "Chromium Embedded Framework.framework" directory with 
Libraries/Resources subdirectories. I've put all libraries/executables in a 
single directory to make it consistent with how it's done on Windows and Linux. 
Also to avoid possible issues with app packagers like pyinstaller.
