Merge branch 'release/0.9.7'

---

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!

 `tablib.Dataset()`
-	A Dataset is a table of tabular data. It may or may not have a header row. They can be build and maniuplated as raw Python datatypes (Lists of tuples|dictonaries). Datasets can be imported from JSON, YAML, and CSV; they can be exported to Excel (XLS), JSON, YAML, and CSV.

 `tablib.Databook()`
 	A Databook is a set of Datasets. The most common form of a Databook is an Excel file with multiple spreadsheets. Databooks can be imported from JSON and YAML; they can be exported to Excel (XLS), JSON, and YAML.
