Chrome Store - text&image update

[xuanqiz]

Since the extension has been updated, we need to update its corresponding introduction/image/contact too.

See the screenshot and corresponding refinement:

iLearn => WeLearn 3 language => 4 (Add Simplified Chinese) ilearn@cri-paris.org => welearn@cri-paris.org

For the demonstration: It's better for us to find an another image to replace this one: (All images has "iLearn" on the left top)

Let me know what I can help you to update all these : )
