Merge pull request #9 from f4nt/tablib

---

I thought I was going to wait til later to do this, but once I got started I couldnt stop myself I guess. I believe this fixes the row limit issues that I mentioned earlier by adding XLSX support. Ive tested it up to 75k rows. Believe the tests and setup.py should be squared away properly as well. Im a bit concerned about the pane freezing stuff, as thats completely undocumented in openpyxl. Truth be told, I barely even know what that functionality does. I hate spreadsheets :)

Anyways, let me know if you want any changes or anything made. Dont have to worry about hurting my feelings or anything!
