Deprecated ambiguous dot syntaxes.

1.+(2) - what is it? Is it 3 or 3.0? Come scala 2.11 you won't
have to not know (or even not know there's something you don't know.)
1.+(2) will then be safely considered equivalent to 1 + 2, because
any dot not followed by a digit is not part of a number.

Primarily, that's these forms:    3.f 3.d 3.

If you prefer an error to a warning, use -Xfuture.

Let's deprecate 012 == 10 too! (See comment.) References SI-5089, no
review.
