Refactored lots of vals to defs, and a few foldLefts to reduces.  Started on problem 36.
fix starting at 10 which was actually a requirement from another problem.  Refactored to collect palindromes of both instead of filtering decimal and then filtering binary.  added minor optimization of only checking odd numbers because of specification in the problem saying it can't have a leading zero and therefore can't have a tailing zero which all even binary numbers would have.  Created isPalindrome method that assumes string because I didn't like looking at a toString on each side of the comparison.
