#11 Spanish datefield

[Hugo Javier Curti]

This patch permits dates to be shown and entered in Spanish format (dd/mm/YYYY). The result of the get command returns the original format (mm/dd/YYYY) to maintain compatibility.

The Tab Key binding was also modified so it behaves as in any other widget (transverse).

The patch was made against iwidgets4.0.0 release sources.
