Review request for KDE Edu and Rahul Chowdhury.


Repository: khangman


Description
-------

Remove duplicate variables for word and current answer.
Rename setLanguage to scanLanguages to explain what it does.
Clean up includes in khangman.cpp.
Initialize m_currentLanguage and m_currentCategory.
Remove level concept, since we use category everywhere instead.
Remove unused private variables.
Add handling of ' - space and middot characters as the old desktop code had.
Remove a couple settings we no longer need or use.

Testing
-------

It builds, runs and no longer crashes on start when there's no ~/.config/khangmanrc file.


Thanks,
