Fix Appoiments and Encounters report to sort by visit date where there is no appointment.
Correct missing instances of xl in various files.
Fix to using most recent development translation set on development demo.

Github can not serve text files are 10MB, so needed a work around. The
development demo now serves this file; this is not ideal since it goes down

Will also direct the wiki link for most recent translation development set
to this file.
