Languages files for the gui

[Torsten]

Dear Translators,

the gui has considerably improved in the recent months and with these
changes the used strings have changed, too. With changeset
http://hg.savannah.gnu.org/hgweb/octave/rev/a12c14aea413
I have pushed the language files (*.ts) updated to the new text strings.
We would really appreciate if you could update the translations. Please
note that the *.tm files are no longer tracked by hg but are generated
during the build process.

So far, there are translations for the following languages:

be_BY.ts
de_DE.ts
es_ES.ts
nl_NL.ts
pt_BR.ts
ru_RU.ts
uk_UA.ts

Is anyone interested in adding another language?

Best regards,
Torsten
