Address book settings: style changes and add NcTextField

[GVodyanov]

Fix #4024

A	B

Changelog:

• Share icon is now square
• Add address book icon has a plus
• Instead of having a boring form and HTML input, we have an ✨NcTextField✨

Small complaint about NcTextField though, to submit you have to use the @trailing-button-click event, and using the Enter key on the field doesn't trigger it

Also, due to the custom event, using min-length doesn't work, and you have to check whether there are any characters inputted in the triggered method.
