Add nb language code for Norwegian.

Previously, the Norwegian language code 'nb' was not recognized by the
datepicker library. This commit adds a file for that code. The
translations are a copy of the 'no' file, only the language code
calls have been changed to use 'nb'.
replace nbsp entity with #160 to allow use with xhtml
