[Xfce-i18n] master, xfce-4-12, and xfce-4-14 ressources on Transifex

[scootergrisen]

When i make string changes on transifex i have to translate the same 
strings multiple times in some projects because it have not only master 
ressource but also xfce-4-12 and xfce-4-14.

Are the xfce-4-12 and xfce-4-14 ressources ever going to be used in a 
release?

I feel like i have wasted time making string changes that is never going 
to be used.

I am talking about these:

thunar.master
thunar.xfce-4-12
thunar.xfce-4-14

xfce4-panel.master
xfce4-panel.xfce-4-12

xfce4-settings.master
xfce4-settings.xfce-4-12
