Activity page with binary files

[segasai]

Hi,

It looks that the current activity page is broken when images/binary files are uploaded In that case the links lead to nowhere. In the patch I fix that by just pointing to the new version of the binary files.

I also space the links to changed files with normal spaces instead of nbsp, as it makes very long lines if multiple files were changed

Feel free to merge or ignore.

Cheers.
Sergey
