ConsoleOutputHandler spell() improvements

[liam027]

ConsoleOutputHandler has method spell() used to type out a message character by character:

    public static void spell(String input) {
        for(int i = 0; i < input.length(); i++) {
            System.out.print(input.charAt(i));
            try {
                TimeUnit.MILLISECONDS.sleep(SPELL_DELAY);
            }
            catch(InterruptedException e) {
                //if interrupted, clear the interrupt flag and continue
                Thread.currentThread().interrupt();
            }
        }
    }

Improvements needed:

• Currently, hitting enter while the message is being spelled out makes a new line and disrupts the message. This should be changed so when enter is pressed the line is immediately completed in full.

• All other user input is still active during spelling (it is possible to type a command and hit enter, during spelling, and it will execute. This should be remedied so user input is accepted only when prompted?
