Now the script just returns instead of exiting with an errorcode. The reason for this is that users can't log in anymore if the specified a wrong path in POWERLEVEL9K_INSTALLATION_PATH and the script `exit`s. With `return` not the whole shell is terminated, so users get an ugly prompt, but are still able to modify .zshrc.
