Modified the addColored and addOutlined methods in the InstanceRenderer class to fix a memory leak. The new code attempts to insert the information in the proper map and if it already exists it will explicitly update the reference to the existing information. The new code no longer relies on the bracket operator of the std::map which was implicitly calling the equals operator of the ColoringInfo and OutlineInfo and causing the memory leak. fixes[ticket:472]
