Respect parmas.dateFmt key's value on /posts/ page

[etanot]

Type: Feature request.

On /posts/ page, datetime format is "2006-01-02", despite parmas.dateFmt key value being set to different value. This happens because we have hard coded the date format for /posts/ page.

It would be nice, if we would respect params.dateFmt key value.

One solution could be replace:

{{ .Date.Format "2006-01-02" }}

with

{{ .Date.Format (default "2006-01-02" .Site.Params.dateFmt)}}

But there is a one problem with this solution, if .params.dateFmt key value also contains time, /posts/ page will also contain time along with date, which I think nobody wants it (i.e. time along with date on /posts/ page).
