[Time applet] No translation for days and months

[wiiznokes]

Currently, it use chrono, with no support for translation

This will probably be implemented with the buildin DATETIME function of fluent. It seems that fluent-rs will support it sooner that later: projectfluent/fluent-rs#181.

https://github.com/kellpossible/cargo-i18n will probably need to make some adjustment after this is merged

[mmstick]

Might be able to use gettext-rs or https://docs.gtk.org/glib/method.DateTime.format.html for that in the meantime, as it has these built in.

I can't find how they handle the case to show the date (since it's not the same order based on locale), and the doc of strftime don't seems to provide a way to display either "14 may" or "may 14", or maybe i misread.
I searched in the gnome panel repo but haven't found.

This is the pr for this #429 , but it still contains some bugs
