New module: Gtef

[Sébastien Wilmet <swilmet gnome org>]

Hi,

Gtef is a new library to ease the development of GtkSourceView-based
text editors and IDEs. It is now hosted on gnome.org:
https://wiki.gnome.org/Projects/Gtef

I see that Gtef is already on Damned Lies:
https://l10n.gnome.org/module/gtef/

Gtef is not (yet?) part of GNOME core. But it is used by LaTeXila, for
example.

Thanks for your translations!

Cheers,
Sébastien
