WW-4551 Adds support for conversion of RFC3339 dates with date part only

> Key: WW-4551
> URL: https://issues.apache.org/jira/browse/WW-4551
> Project: Struts 2
> Issue Type: Improvement
> Components: Core Actions
> Affects Versions: 2.3.24
> Reporter: Andrea Ligios
> Assignee: Christoph Nenning
> Fix For: 2.3.x
>
>
> Facts:
> - {code:xml}<input type="date" />{code} is the HTML5 standard for inputing
> dates. It works in many browsers: Chrome, Opera, almost every mobile browsers
> - where it is fundamental - and the coverage can only grow.
> - [w3 has chosen the RFC3339 *with date
> only*|http://www.w3.org/TR/html-markup/input.date.html#input.date.attrs.value]
> as *value format* {code}yyyy-MM-dd{code} while transparently handling the
> *display format* according to the Locale.
> This means that, for example, americans see {code}MM/dd/yyyy{code}, italians
> see {code}dd/MM/yyyy{code}, but both of them send {code}yyyy-MM-dd{code} to
> the server. *Without the time part*.
> - Struts Date Converter already works for:
> {code:title=DateConverter.java|borderStyle=solid}
> DateFormat dt1 = DateFormat.getDateTimeInstance(DateFormat.SHORT,
> DateFormat.LONG, locale);
> DateFormat dt2 = DateFormat.getDateTimeInstance(DateFormat.SHORT,
> DateFormat.MEDIUM, locale);
> DateFormat dt3 = DateFormat.getDateTimeInstance(DateFormat.SHORT,
> DateFormat.SHORT, locale);
> DateFormat d1 = DateFormat.getDateInstance(DateFormat.SHORT, locale);
> DateFormat d2 = DateFormat.getDateInstance(DateFormat.MEDIUM, locale);
> DateFormat d3 = DateFormat.getDateInstance(DateFormat.LONG, locale);
> DateFormat rfc3339 = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
> {code}
> with a final fallback to {code:java}DateFormat.SHORT{code} if nothing worked
> (in case of Time and Timestamps too).
> My idea is:
> can we add the support for *date-only RFC3339*, that is the one sent by the
> browser, *in addition* to the ones already there ? No existing code would
> break, and we'd have a standard, automatic conversion for a popular, growing
> *standard*.
> I can't see any cons. Can you ?
