Bug 14812: Display the help in the correct language

If opaclanguages != language, the language of the help page is the
default one (en).

Test plan:
1/ Set language to en, fr-FR, ar-Arab and opaclanguages to en, fr-FR
2/ Translate the fr-FR and ar-Arab templates.
3/ Go on the mainpage, switch to ar-Arab, go to the help page.
The help page content should be in Arabian, not English.

Set language = en, sv-SE, nb-NO. opaclanguage = en, nb-NO
Went to the intranet main page, selected Swedish and clicked on help
Without the patch, help was displayed in English
With the patch, help was displayed in Swedish. Yay!
