Bug 7038 Contextual help is always in English

When another language than English is selected in pro interface, the software
strings are in this language, but when clicking ?, on the top right of any
page, the contextual help page which pop-up is always in English.

This patch fixes this bug and another side bug affecting editing contextual
help when not in English. help.pl script were in sync with the recently
patched/improved theme/language/template selection.
