I'm sorry I didn't catch about this in the previous discussion, but how about
putting the foreground, the background, and the common directories in the js
directories?
In the current structure, it seems that background and common directory has just
one js directory and it looks redundant for me. WDYT?

Sorry I didn't say that I've change the mind, but I now think it's better to
split just under file_manager directory.

As you said, almost all images are under foreground, some are under common (eg.
icons, and file-type images) and no one under under background. But I think it
looks good since almost all images are used from foreground, and this is just
what the structure is.

In the feature, the 'foreground' may be able to be organized more, eg. into
file_manager, photo_importer, video_player,... etc. I think this structure is
better when we do the future organization.
