Resource bundle markers only work in connection with jahia_multivalue

According to the tests in the "Default values" template the "Resource bundle marker" only works in connection with the jahia_multivalue keyword, that means only when there is a choice list and NOT when I want to set a single default value from a resource bundle. If this is a wanted limitation, it clearly has to be documeted that way in the "Template Developer Guide", because according to the current description you could use a resource bundle marker for the default value without limitation.

I have tested for SmallText, SharedSmallText, BigText, Float, Integer and it is not working. If we decide that it should work, we should perhaps consider also the other types, if it makes sense.
