renderDateTimeField Freemarker macro ignores framework date-time format settings

http://ofbiz.135035.n4.nabble.com/renderDateTimeField-Freemarker-macro-ignores-framework-date-time-format-settings-td3965275.html#none

The renderDateTimeField macro in htmlFormMacroLibrary.ftl ignores the
framework date-time format settings and formats date-time fields using
jQuery instead. Two problems with that:

1. Even when shortDateInput = true, the date and time are displayed when
the value is a Timestamp.
2. If the value is anything other than a Timestamp, (java.util.Date or
java.sql.Date) then the field content is localized, and any attempt to
pass the field content to a service fails - because there is no way to
convert the string back to the proper object type.

Why was this change made?

I located the problem and committed some notes in rev 1197028. I don't
have time right now to fix it.

The problem isn't caused by JavaScript, it's caused by the renderer. We
still need to fix the JavaScript code though.
