Don't try to indent case or default statements

Using the current regexp-based indentation system, we either
have to indent these statements the way that textmate does,
which is non-standard, or the way sublime does, which requires
the user to manually type tab after a case or default statement.
I've chosen sublime's way for now, because it makes it easier
to achieve the most common indentation style.

Closes #49
