Removed book that is no longer free

Added several books to Mathematics and one to R

Added books to Datamining and Machine Learning sections

Added Network Science book to Theoretical Computer Science section

I had believed that this book was free, I think at some point it was,
but following a comment from johand, it is clear that this is no longer
the case, and a result, not suitable for this list.

Added 6 statistics books to Mathematics section and one book to the R section

I'm not sure exactly what section this belongs in; it seems to be influenced by several fields.  If someone else knows a better section, I'd be happy to move it.
