Moved the "Welcome box block" installation inside a config.yml file. - The "only display on front page" function still doesn't work.
Renamed the "themes" stylesheet files to "color-schemes" since it's more descriptive and added basic support for frontpage-teasers in the schemes.
Added color scheme selection on "Frontpage Teasers".
We now output the "Color scheme" values on frontpage teasers as classes (color-scheme__xxx)
Added basic styling for the welcome box
