Description
From CLK-624:
Before we all go ahead and submit translations for month and day names (and abbreviations), I think it would make more sense for DateField to generate these names from here:
http://java.sun.com/j2se/1.4.2/docs/api/java/text/DateFormatSymbols.html#getMonths%28%29
http://java.sun.com/j2se/1.4.2/docs/api/java/text/DateFormatSymbols.html#getShortMonths%28%29
http://java.sun.com/j2se/1.4.2/docs/api/java/text/DateFormatSymbols.html#getWeekdays%28%29
http://java.sun.com/j2se/1.4.2/docs/api/java/text/DateFormatSymbols.html#getShortWeekdays%28%29
By creating the arrays from java's names we will AFAIK also instantly "support" all language so that DateField.SUPPORTTED_LANGUAGES can be removed.
