Bugfix release 4.5.2

Version 4.5.1

Version 4.5.0 releaase

Bump to version 4.4.1, updated README and HISTORY

Updated for pacman 6.0

- Compatibility with pacman 5.1

- Fix not being suspend-aware

- Add popup menu on "Mark Watched (AUR)" to (un)check all

With contributions from Bricabraque & pepecuis.

- kalu: Add --tmp-dbpath and --keep-tmp-dbpath

Mainly useful for CLI use (or not?), to be able to keep & re-use the tmp dbs
over time, much like the GUI does during its run.

- Add Spanish translation; Thanks to pepecuis!

- Support disabling auto-checks (via Interval = 0)

- news: Fix issue if title needs trimming..

..that is, if a news title (used to determine whether it has been read
or not) could be trimmed, there was an issue because titles read from
news.conf are trimmed, so the two wouldn't match, and the news
incorrectly considered unread.

To fix this we trim the titles read from the XML (RSS feed) as well.

Thanks to Ada Joule; Also adam777 for the report.

- Update French translation

- doc: Adjust example path about custom icons

- doc: List options in alphabetical order

- Some other fixes (see git log for details)
