[Xfce-i18n] New strings in Thunar

[Baurzhan Muftakhidinov]

Hi,

I noticed that there are couple new strings in Thunar,
and one of them is below

Thunar is a file browser specifically designed for the XFCE Desktop,
but also can serve as an alternate file browser for other Desktop
environments. It has a simple, clean two-pane design for browsing all
your files.

Why XFCE is all capitals? According to https://wiki.xfce.org/faq
it must be Xfce with only X capitalized.

Please review and correct,

Thanks
