This adds a scale to change the color temperature from 3000K to
6000K. A mark is added to the default value and a second one for
aesthetics.

Presumably, they are nonwritable because a system administrator has locked
these settings down.

If Night Light is locked on, don't show the Off button.
If Night Light is locked off, don't show the Manual or "Sunset to Sunrise" buttons.
If Manual is force-enabled, don't show "Sunset to Sunrise" or the other way around.
This commit improves the Night Light code in various
ways:
* Turn it into a template class, subclass of GtkDialog,
and adapts all the code to reflect that.
* Update the code style in various places, to make it
more conformant with the documented code style.
* Reorganize the code a bit, moving functions around,
to make it more conformant with the documented order.
dialog_got_proxy_cb and dialog_got_proxy_props_cb may be called after the
instance of CcNightLightDialog has been disposed. Make sure 'self' pointer is
not dereferenced if not valid.
Fixes: https://gitlab.gnome.org/GNOME/gnome-control-center/issues/86
The night light schedule dialog stores the time as a single floating
point value, which is then converted into hours and minutes for the
time selection fields.
Previously, the minutes were calculated using the remainder of the
stored value and the hours. This caused undesired behaviour when the
hour field was set to zero, as fmod(value, 0) returns NaN. As a result,
the user was not able to set the time between 00:00 and 00:59.
This patch rewrites the time retrieval logic using modf.
