Date picker localization in RO

The RO localization file has the following mistakes:

dateFormat should be 'dd.mm.yy' and not 'dd MM yy' because

• the month indicator for datepicker is mm and not MM
• the date separator in Romanian is the dot, not the space

This rends the intialization of a datepicker control useless, since it does not recognize the initial date format in the attached field.

weekHeader should be 'Săpt' and not 'Sapt'

This is minor
