[jitsi-dev] Update for Asturian language

Hey there.

I'm Llumex03, the translator of Jitsi proyect for Asturian language.

I request to update the .po file from translate.jitsi.org to the git
repository of the Asturian language, It is necessary because i had to
update the full translations to use the new glosary. However, i'll make a
new .properties file of my language and create a pull request in GitHub.

Thank you so much. Bye
