Add a date picker (calendar) in the Daily page

[nodiscc]

Probably better to do this after #160.

The calendar could allow picking a particular date, or a date range.

I implemented one into (old version) of albinomouse : https://github.com/alexisju/Shaarli-AlbinoMouse/blob/master/tpl/daily.html

But it's not perfect:

• if you choose a day without links, you don't have warnings,you have to set up a manualy a beggining date (first published link)...
• its slowdown shaarli (it's why i implemented it only on the daily)

(and my code is ugly : loading to much js librairies)
