[E-devel] [PATCH] Elementary label wrapping support

[Treviño]

I've made a small patch to give to elm_label the same text wrapping
functionality that elm_entry has.

So a new API has been defined:
   EAPI void elm_label_line_wrap_set(Evas_Object *obj, Eina_Bool wrap);

Maybe it should be enabled by default, but for now I've kept the
previous implementation as the primary one.
