 * Fix wallpaper import on language with floating point separator different that ','

The edc was generated as

   align: 1,3333 1,333;

and thus edje_cc refused to build.

I have done a quick HACK. simply set locale to "C" and the reset to previous locale.
If someone know a cleaner way to solve this issue please let me know.

POSSIBLE ALTERNATIVE SOLUTION:
Why we don't make E able to directly load image files?
I think it's just a matter of 2 lines of code...or am I wrong?
Doing this we can remove all this hackish code to generate edc.

Thanks
Dave
