defaults.lua: add a disabled parameter to timer constructors

Browse Source 
Added to the functions `mp.add_timeout` and `mp.add_periodic_timer`.

If the `disabled` argument is set to `true` or a truthy value, the
timer will wait to be manually started with a call to its `resume()`
method.

@ -438,17 +438,21 @@ The ``mp`` module is preloaded, although it can be loaded manually with
that are equal to the ``fn`` parameter. This uses normal Lua ``==``
comparison, so be careful when dealing with closures.
``mp.add_timeout(seconds, fn)``
``mp.add_timeout(seconds, fn [, disabled])``
Call the given function fn when the given number of seconds has elapsed.
Note that the number of seconds can be fractional. For now, the timer's
resolution may be as low as 50 ms, although this will be improved in the
future.
If the ``disabled`` argument is set to ``true`` or a truthy value, the
timer will wait to be manually started with a call to its ``resume()``
method.
This is a one-shot timer: it will be removed when it's fired.
Returns a timer object. See ``mp.add_periodic_timer`` for details.
``mp.add_periodic_timer(seconds, fn)``
``mp.add_periodic_timer(seconds, fn [, disabled])``
Call the given function periodically. This is like ``mp.add_timeout``, but
the timer is re-added after the function fn is run.
