OffsetDateTime JSON serialisation format is not parsable in JavaScript

[GoogleCodeExporter]

As noted in http://stackoverflow.com/q/23828573, the JSON serialisation format 
for OffsetDateTime produces output such as "2014-05-16T07:28:51+02" (it uses 
OffsetDateTimePattern.ExtendedIsoPattern).

However, ECMA-262 requires that the offset be specified including the minutes 
(see http://www.ecma-international.org/ecma-262/5.1/#sec-15.9.1.15), and at 
least Chrome fails to parse the string otherwise:

> Date.parse("2014-05-16T07:28:51+02")
NaN
> Date.parse("2014-05-16T07:28:51+02:00")
1400218131000

(The spec _also_ requires the milliseconds field, if present, to be three 
decimals, rather than the six we generate. However, that appears not to cause 
trouble in practice, so we might not want to change that.)

While JSON doesn't necessarily mean that you're parsing with JavaScript, it 
seems reasonable to at least consider changing the serialization format to 
always include the minutes.

Right.  I believe this is also a requirement of RFC3339.

Fixed the Json.NET representation in revision a24b462035cd.
However, I've just tried this for the XML representation, and that has the same 
issue - in particular, the conversion from XElement to DateTimeOffset fails 
unless the offset is in HH:mm format.

It's unfortunate that we won't be able to round-trip values, but I think we 
should change the XML representation too...

XML representation changed in revision ce2d2662a0b0. I think we're done now; 
I'm not changing any non-serialization formats at the moment.
