Endnote tagged items will not import

Problem/Motivation

Windows newline characters (\r) are not properly handled, and thus the endnote will not import.

Steps to reproduce

- Download an endnote tagged file from Google Scholar (for example: https://scholar.google.com/scholar?oi=bibs&hl=en&cites=37447847387266719...)
- Try importing.

Proposed resolution

- Trim the values when normalizing the data.
