#1312 Mac install does not include any dictionary, so spell checker displays message

[Andrew Cottrell]

C::B on a MAC does not include any dictionaries like on Windows. As such when you run C::B the spell checker displays a message to say you need to manually install a dictionary.

I would suggest moving the dictionaries from the Windows C::B installer directory into the /src/plugins/contrib/SpellChecker/dictionaries directory. The Windows CB install NSIS sctipts would also need to be changed to get the dictionaries from the plugin directory.

This would allow the MAX DMG creation scripts to use the dictionaries from the plugin directory in the future.
This would allow the Linux build scripts to access the dictionaries as well in the future.
