Made README.formattedIO more consistent w.r.t. "integer" and "integral".

* Chapel integral types are denoted by "integral".
I did my best to use "integral" wherever there is a reference
to those Chapel types. Except...

* "signed integer" means int(?),
  "unsigned integer" means uint(?).

* Just "integer" means either an integral value unrelated to Chapel
types, or one of the above where its Chapel type should be clear from
the context.

* "number" refers to some numeric value whose Chapel type (if
applicable) should be clear from the context.

* Clarified that %i applies only to signed integers; %u applies only
to unsigned integers.

* Changed "number" --> "integer" for Integral Conversions, except
where deemed unnecessary.

* Qualified all uses of "integer" with "signed" or "unsigned",
except: the second part of Integral Conversions (where %i has already
indicated these are signed) and a couple of other places where
I deemed such qualification unnecessary.
Hm, by the same token replacing "number" -> "integer" for Integral
Conversions is unnecessary, but it seemed more important so I did it.

* Unrelated: corrected %y -> %S, and a couple of minor embellishments.
