[O] [feature request] Plain list item timestamp support

[Marco Wahl]

Hello Orgers,

As you possibly know [see (info "(org) Timers")] list items created with
M-RET get prefixed with the current timer value when they match a
certain form.

#+BEGIN_EXAMPLE
* Work so hard

- 0:00:00 :: Start
- 0:00:03 :: Working so hard

M-RET (with timer on 0:00:30) yields the line

- 0:00:30 ::
#+END_EXAMPLE

I suggest to implement the same mechanism for inactive timestamps.

#+BEGIN_EXAMPLE
* Work so hard

- [2016-06-11 Sat 15:33] Start
- [2016-06-11 Sat 15:34] Working so hard

M-RET (when the current time is [2016-06-11 Sat 15:35]) yields the line

- [2016-06-11 Sat 15:35]
#+END_EXAMPLE

WDYT?


Best regards,
