Whitespace fixes to patch
Reduce image size.

Checking the site with the PageSpeed extension, one of the reports was
in reducing image size.  This reduced the number of bytes by 67%.

It was done with optipng -o7 -fix *.png in the app/assets/images dir.

Ran optipng -o7 -fix over all png files. This should make pages load a
tiny bit faster (you can test this with the pagespeed tool on firefox or
chrome).

It might be an idea to add *lossless* image compression optimization
runs to the release process.
