FYI: gnome-terminal help pages

[Egmont Koblinger <egmont gmail com>]

Dear Translators,

This is just a friendly heads-up:

gnome-terminal's help pages received lots of changes about a month
ago. The pages were updated against the new merged preferences window,
plus they received many one-off fixes as well.

There are several languages where these pages were 100% translated in
3.26, but are at 72% now. In case you have time, it would be awesome
if you could update them so that they don't regress. These languages
are: ca cs de el es fr hu ko pt_BR sv. Also in quite good shape,
probably worth completing are: fi ru.

Special thanks go out to Piotr Drąg for his continuous effort on
fixing the source strings, and the completeness of the Polish
translation!

Thanks for your great work guys,

Egmont
