[Dextrose] [PATCH sugar] Adding a "hook"-function, that is called when the "OK" button in the SectionView Toolbar is clicked.

[Ajay Garg]

Making use of this hook-function in "DateTime" and "Network" CP views,
to get rid of the "Save" button in the "NTP Servers Configuration" and
"Hidden Networks" sections respectively.

Thanks to Anish for the motivation.
