Each of these strings would previously rely on StringView's char const*
constructor overload, which would call __builtin_strlen on the string.
Since we now have operator ""sv, we can replace these with much simpler
versions. This opens the door to being able to remove
StringView(char const*).
No functional changes.
Previously guesses were not checked which allowed guesses
like 'aaaaa' to be entered.
Currently there's an option to set if a guess should be checked
against the dictionary and rejected if it doesn't exist there.
Additionally settings from Game menu have been moved to its own
entry - Settings.
