Untranslated buttons in spam filter admin panel

[Jun Omae]

After [14814,14815], labels in the buttons of spam filter admin are untranslated.

The gettext in tracspamfilter.api is not the same as gettext in trac.util.translation. Instead, we should use dgettext and dngettext with tracspamfilter catalog like this:

-        <input type="submit" name="cleantemp" value="${ngettext('Remove %(num)s temporary session',
+        <input type="submit" name="cleantemp" value="${dngettext('tracspamfilter', 'Remove %(num)s temporary session',

Those translation methods can easily be replaced by sed.

for i in tracspamfilter/templates/*.html; do
  sed -i \
    -e "s/\<_(/dgettext('tracspamfilter', /g" \
    -e "s/\<gettext(/dgettext('tracspamfilter', /g" \
    -e "s/\<ngettext(/dngettext('tracspamfilter', /g" \
    $i
done
