NEWS: add periods to sentences, order by subject

This is always a bit subjective, but I find a NEWS file much easier to read if
it's thematically organized. I think support for a new distro is important, so
put that first, then new verbs and options, then new configuration features,
and then all the other smaller changes.

   repository. Profiles can be defined in `mkosi.profiles/` and one can

-- Added a `--json` option to get the output of `mkosi summary` as JSON.
-- We now automatically configure the qemu firmware, kernel cmdline and
-  initrd based on what type of kernel is passed by the user via

+- Added `ToolsTreeMirror=` setting for confuring the mirror to use for

   have finished executing.
+- Added `QemuDrives=` to have mkosi create extra qemu drives and pass
+  them to qemu when using the `qemu` verb.

 - Workspace directories are now created outside of any source
   directories. mkosi will either use `XDG_CACHE_HOME`, `$HOME/.cache` or
   `/var/tmp` depending on the situation.

-  (`docs/building-rpms-from-source.md`)
