Improve constructor rustdocs for Address

tcharding · tcharding · commit 822c99222d6e · 2021-11-19T09:42:19.000+11:00
Improve the rustdocs for the various `Address` constructors by putting
the brief description on a separate line with further description in its
own paragraph. This is the layout best practice for function documentation
using rustdocs.

Also, favour 'creates' over 'constructs' because it is more common in
the docs of this struct.
