Sets a direct double if token type is formula::svDouble, or mbEmpty if formula::svEmptyCell, else token.

If p is NULL, that is set as well, effectively resulting in GetType()==svUnknown. If the already existing result is ScMatrixFormulaCellToken, the upper left is set to token.

ATTENTION! formula::FormulaToken had to be allocated using 'new' and if of type formula::svDouble and no RefCount was set may not be used after this call because it was deleted after decrement!
