Removed several unused methods.

Could not remove ScVbaFormat<ooo::vba::excel::XStyle>::getAddIndent() and ScVbaFormat<ooo::vba::excel::XStyle>::setAddIndent(com::sun::star::uno::Any const&) because it breaks compilation (they are implementing pure virtual methods).
Should Test::test1Table1Page() really be removed? (test class)
