In OOXML a color definition includes more represenations, one of which is scheme color (which is what is implemented in ThemeColor currently), but it supports other representations too (RGB, HSL, System,..). ComplexColor includes all the representations, so to have a better compatibility with OOXML, this changes all uses of ThemeColor to ComplexColor. In many cases the usage of ComplexColor isn't the same as the usage of ThemeColors, but this cases will need to be changed in a later commit.
