Add short date/time output formats
Imported From: http://groups.google.com/group/in-portal-dev/browse_thread/thread/2c000291074a71f5#
Currently each In-Portal language has a bunch of formats used to input/output date and time when user is viewing website on that language.
However we are surely missing following formats:
short date output format (usually without year), e.g. "m/d"
short time output format (usually without seconds), e.g. "h:i a"
By default these formats won't be used, but developer can start using them any time, when there is a need with following tag:
<inp2:unit-config-prefix_Field name="DateField" format="_regional_ShortDateFormat"/>
<inp2:unit-config-prefix_Field name="TimeField" format="_regional_ShortTimeFormat"/>
