Standardize on ISO 8601 date format

[timb07]

At /list#/roles, the Last Commit and Last Import dates are in MM-DD-YYYY format, while on individual role pages, the format is MM/DD/YYYY. I find both of those confusing, the latter because (as an Australian) I'm used to seeing DD/MM/YYYY, and the former because when I see dates with hyphens I automatically think ISO 8601.

May I suggest the use of ISO 8601 date format (YYYY-MM-DD) throughout? xkcd makes the best argument for it.

Agreed, we should standardized the date format. Not sure how I feel about using the ISO 8601, but you might be right. It feels a little nerdy, but it does make sorting things easy.
