From: WooHyun Jung <wh0705.jung@samsung.com>

Mr. Wonguk Jeong made a patch for elm_module.

This patch is for changing the timing of module loading.

 For now, module loading is done in elm_init

 Thus, modules are always loaded, even if the application does not use
them.

 So this patch deferred the timing of module loading to
 "_elm_module_find_as".
