Add ISO's YYYY-MM-DD date format to general settings

[mattheweppelsheimer]

The ISO's 8601 specification states that digitized dates should be specified in most to least significant time period, separated by hyphens. YYYY-MM-DD is the recommended format. The closest default we have currently is YYYY/MM/DD, but I'd like to see this international standard represented in the default list.

​Wikipedia's page (accessed 2014-06-03) has more information — see the third bullet of General Principles. Here is the ISO's ​8601 FAQ page.

This patch adds this standard format to the default array of date formats.

Can we move this up to be next to the Y/m/d option? I also feel like this somehow tips into being too heavy - not sure if another option could be eliminated.

[gauravmittal1995]

If we are including the "Y-m-d" format, do we remove the Y/m/d format?
ALso we can replace the "m/d/Y" and "d/m/Y" with "m-d-Y" and "d-m-Y". This will go well with the "Decisions, not options" philosophy.

Replacing of a/b/c format with a-b-c" format.

m/d/Y appears to be a common format in the United States. We could probably replace Y/m/d with Y-m-d though. For reference: ​http://en.wikipedia.org/wiki/Date_format_by_country#Listing.

According to he more popular choices (refer: ​http://en.wikipedia.org/wiki/Date_format_by_country#Listing )

28447(2).patch​ looks good to me.

According to the listing above, Y-m-d is definitely more popular than Y/m/d. Translation teams can still set their own preferred format in language files by translating the default format, F j, Y.
