Removed Tutorial from templates/root.html (Issue #23)
Added a sentence for troubleshooting topics in README.md -> Recommends to go to Wiki. So we don't have to change the hhu_theme repo every time we want add some troubleshooting information.
Merge pull request #47 from skoenen/master

Adding a hint, where to get information for troubleshooting
Made templates/badge/tiles.html(def badges) skip badges with color: '#fff'

Using a colorcode is necessary, because of the javascript spectrum colorpicker,
that is used to select a color for a badge.

Closes #45
Merge branch 'master' of github.com:hhucn/adhocracy.hhu_theme
+ Changed the spectrum javascript colorpicker to recognize non color codes.
+ Changed badges/form.html to include the javascript in theme dir
+ Changed components.html to use the spectrum.css in javascripts/spectrum instead of the adhocracy/static/javascript/spectrum one

+ Changed badge/tiles.html to only render badge if color is not equal 'invisible'

TODO: Make a minimize version of spectrum.js
Added color == invisible proof to the render facets, so invisible badges do not show up in the sidebar.
Removed spectrum colorpicker from theme -> moved to adhocracy
