Allow projects to append or override the default CSS

At the moment project-specific CSS always completely overrides the
default CSS. This is bad if projects just want to make a single
modification because it would require to copy the complete default CSS
and then change it. Add a new formatter config option to control
whether the project-specific CSS should be appended to the default CSS
(default case) or whether the project-specific CSS should completely
override the default CSS.
