* Moved some settings keys into new files SettingsKeys.h/cpp to make it less

likely to introduce erros with spelling settings keys wrong somewhere.
* Introduced new setting for the behavior if tabs should show at all if only
  one page is showing in a window. Defaults to on, i.e. the previous behavior.
