Changing states in program enrollments portlet handles dates incorrectly in Portuguese, Italian, and Spanish locales.

the patientPrograms.jsp file (in the portlets folder) still has some really old hacky code I wrote in 2006 to format and parse dates. It specifically treats the en_GB and fr locales as DMY, and all others as MDY.

First, do a quick-fix to also treat pt, it, and es as DMY, and get this committed ASAP.

Then, refactor this portlet to use a proper library function for date conversion (and remove my hacky 2006-era code).
