i3status-rust: update it to handle 0.30.x releases (#3773)

* i3status-rust: update it to handle 0.30.x releases

0.30.0 is a major release that brings many breaking changes to the
configuration file. See:
https://github.com/greshake/i3status-rust/blob/master/NEWS.md#i3status-rust-0300

The only one that actually affects the module though is the change in
how the theme/icons are defined. Other changes are mostly on how to
specify formatting/blocks, and since we just generate the TOML as-is, it
needs changes in the user side.

So most changes in this commit are documentation updates, having
up-to-date examples from things that changed, e.g.: the new `click`
attribute that now can be applied to any block.

* i3status-rust: only use new format if i3status-rust >= 0.30.0

* news: document the i3status-rust changes

* i3status-rust: add thiagokokada as maintainer
