This introduces the STVar container, capable of holding any STBase-derived class and implementing a "small string" optimization. STObject is changed to store std::vector<STVar> instead of boost::ptr_vector<STBase>. This eliminates a significant number of needless dynamic memory allocations and deallocations during transaction processing when ledger entries are deserialized. It comes at the expense of larger overall storage requirements for STObject.
