Added a new component docmodel, that has the document model types,
which only depend on other basic components. This is needed so the
types can be used in every relevant component - xmloff, oox, svx,
editeng,...
Introduces model::ThemeColor, which is a class used to store the
theme color data, including transformations (svx::Transformation).
For UNO use XThemeColor is added, and the implementation UnoThemeColor
which wraps svx::ThemeColor, so it can be tranported around.
Reactor all the code and tests to accomodate for this change.
