internationalization - calendar display

[jrmartino]

Calendar display is another major issue. Currently, the calendar is labeled consistenly with usage in France. Changes would need to be made to make sure that long and short labels for both month and day of week are localized, as well as the start day of the week. Again, it would seem that this can all be handled in the UI with the appropriate macros and perhaps a little hacking with javascript.

To reproduce: create an appointment calendar, and display it in a browser which has en-us set as the locale. You wuill see all labels displayed in French, with the standard French week starting on Lundi instead of Sunday for en-us.
