join() does not support array iterable

What steps will reproduce the problem?

Lambda.join(new String[] { "a", "b", "c" });

What is the expected output? What do you see instead?

returns "[Ljava.lang.String;@..." instead of "a, b, c" as expected. This should 
work the same as the other methods that work on collections, maps and arrays.

What version of the product are you using? On what operating system?

lambdaj 2.2 on Mac OS X 10.6

Please provide any additional information below.

I don't have enough knowledge of the inner workings of lambdaj to provide a 
patch, but this shouldn't be too hard to fix if the patterns from other methods 
are followed.
