According to [1], the string "This could be the result of
the graphics driver being used, or the desktop being used
remotely" should end with a period. This wasn't addressed
in [2], so add the period to fix this issue.

Night light can be unavailable in three cases:
- Device being used remotely
- Unsupported graphics driver
- Using a virtual machine
In all of these cases, a GtkInfoBar is shown. However, GtkInfoBar is
deprecated. AdwBanner is the replacement, but it's meant for short
text and the text explaining the three cases above is quite long for
AdwBanner. AdwStatusPage can be used with longer text, so use it.
Using `g_clear_handle_id()` in combination with `g_source_remove()` can
save a lot of boiler plate code.
This removes about 110 lines of code for free.
g-s-d was changed to use a better black body temperature calculation.
This strongly affects the effect of the color temperature (the default
is changed from 4000K to 2700K). Update the scale to represent a similar
range to default even if the distribution on the scale is quite
different.
The new Night Light page, as described by the latest mockups [1],
uses a listbox to display the options. Also, there is a small
revamp on how the disabled state is handled; it now is a switch
in a row, instead of an extra radio button.
This commit changes the Night Light page to have a listbox, and
uses libhandy's rows to achieve the desired interface.
