Spruce theme from http://bootswatch.com/spruce/ for Kotti.
To activate the kotti_theme_spruce theme in your Kotti site, you need to
add an entry to the kotti.configurators setting in your Paste
Deploy config. If you don't have a kotti.configurators option,
add one. The line in your [app:main] (or [app:kotti], depending on how
you setup Fanstatic) section could then look like this:
kotti.configurators = kotti_theme_spruce.kotti_configure
