Recompiled usermanual.

This can't be causing the failure can it? It can't find QtMultimedia..

Dunno how I missed that.

Fix #128

Use cpack to create osx's dmg

Check for path creation failure

Fix #88

This has been obsolete a long time

Ref #112

Ref #109

If the sounds path is unset in the settings and a “sounds” directory
doesn’t exists in the user’s data directory, install the sounds files
and set the settings value accordingly

 If none of the gameboard images is set and and the user’s data
directory doesn’t contain a “zonebg” directory, create the directory,
copy contents from cockatrice’s app bundle and sets the config
accordingly.

Without this change, make install and make package would require “sudo”
under osx

By now tested on OSX only
