Core pr 5

Added drush extension (cgen) to generate css with color changes.
Added auto log out.
Removed secure pages.

We have a lot of problems with the color module in production and the hosting partner needed a way to regenerate the stylesheets after a update of the theme. This would require that all libraries would go to the theme settings and pressing save.

So the drush commando "cgen" do this and helps on the upgrade path.
