Add support for formatting date and datetime using userlocale

Currently, to use the FORMAT_DATE function, you must specify the format to use.  In a globalized application, date/time formats are not always the same.

Would like to see support added for the following:

1) FORMAT_LOCALEDATE(date) function
2) FORMAT_LOCALEDATETIME(date) function
3) Expore skuid.utils.userLocale in Global merge variables

Thank you!

Thanks for your suggestion on how to make Skuid more user friendly. The devs are aware of your idea and will consider it for a future release.

Thanks for helping us make Skuid better!
