ImageGallery use appropriate lang.
ImageGallery always uses the user interface language, which sometimes is
bad if the gallery is on a content page via <gallery> or an extension.
I have a patch to fix this, but I'm not sure I like it (attached) So adding to bug for now while i think about it.
This issue is rather minor since it mainly affects the showfilesize
option, which is not triggerable from the <gallery> tag hook,
however some extensions output galleries in content pages too.
what this patch does is:
Add a method to trigger using content language instead, and also
get the language object from parser if parser object is available.
(Would Context something or other be better?)
