Subject: Elm gettext: Only translate if the app using elm is translatable.
X-Git-Tag: REL_F_I9500_20120323_1~17^2~1779
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=89c763f9e612f14ce97b8a081e666e242a49c129;p=framework%2Fuifw%2Felementary.git

Elm gettext: Only translate if the app using elm is translatable.

It assumes gettext is initialized before the call to elm_init.
