DecimalFormatSymbols.java: Added the year 2007 to Copyright information and introduced new variable, currency.

2007-04-04  Tania Bento  <tbento@redhat.com>

	* java/text/DecimalFormatSymbols.java: Added the year 2007 to
	Copyright information and introduced new variable, currency.
	(DecimalFormatSymbols(Locale)): Define currency and intlCurrencySymbol
	to "XXX", currencySymbol to "?" and localCurrency appropriately.
	(getCurrency): Fixed documentation and return the value of currency.
	(setCurrency): Fixed documentation and update the value of currency.
	(setInternationalCurrencySymbol): Fixed documentation and update the
	value of currency.
	* java/util/Currency.java: Introduced two new variables, properties
	and fractionDigits. In the static block, a properties object is
	created and the currency resource is loaded.
	(Currency(Locale)): fractionDigits is defined.
	(Currency(String)): New method.
	(getDefaultFractionDigits): Return the value of fractionDigits.
	(getInstance(String)): Check if String is equal to "XXX".
