Add myAPIkey.txt to the .gitignore

Thanks to Blake Naccarato for the suggestion to add myAPIkey.txt to the
.gitignore to prevent accidentally committing your personal API key to a
public repository.

Also add additional standard MATLAB file types that should be ignored,
including autosave files, compiled files, and other cached files.
