Merge Player fixes

Just a minor release, fixed a few issues with merging players throwing errors because I forgot to re add some functions after removing them.

To upgrade from v2.10.1 follow this pages instructions: https://github.com/scottadkin/node-utstats-2/releases/tag/v2.10.2, if you are upgrading from v2.10.2 you don't need to run npm install or node upgrade, just stop the website & importer and replace the files from the archive.
