Objects Everywhere (#3)

Building on the previous exercise, strip out special characters before testing. "Madam I'm Adam" should now be considered a palindrome.

Build a new String consisting of letters only, and check whether it's a palindrome. Use in to check whether a character is a letter: ch in 'a'..'z' || ch in 'A'..'Z'.
