Incorrect results for machine (and other mac-y words)

[David Byers]

>>> titlecase("macho men eat macaroni and macaroons like machines")
'MacHo Men Eat MacAroni and MacAroons Like MacHines'
>>>

Handling of the "Mac" prefix is necessary, but so is a list of exceptions to the rule.

[David Byers (david-byers)]

If this is left unfixed, I will eventually provide a patch for it (it will necessarily be a bit more complicated than just a list of exceptions).

[Joseph Price (pricejosephd)]

I went with the exceptions list so far on my branch, but I'll be digging into a better method sometime soon.

If I don't come up with a fix, I'll just expand the exceptions list.
