rock paper scissors with random computer

@gabebw @jsteiner
I had 
if user_won?
puts "user won"
elsif user_tied?
puts "tie"
else 
puts "computer won"
end

but i thought it was too many lines and I had to shorten it so that's why I did a post-conditional.... I can't think of any other way to shorten an if, elsif, else statement - is there?
