Stata-kernel

- Add pywin32 as a pip dependency on Windows, thus making installation easier.
- Add jupyter 1.0.0 metapackage as a dependency, so that installs from Miniconda also install all of Jupyter.

- Fix issues with `--more--`. 103
- PDF Graph redundancy. This improves ease of export to PDF via LaTeX.
- Catch PermissionsError when copying syntax highlighting files
- Add Stata logo for Jupyter Notebook
- Autoclose local macro quotes in Jupyter Notebook
- Highlight /// as comments in Jupyter Notebook
- Highlight macros in Jupyter Notebook
- Check latest PyPi package version and add alert to banner if newer
- Simplify `%set` magic
- Set default linesize to 255 for now to improve image handling. 177

- Add CodeMirror syntax highlighting for Jupyter Notebook
- Improve Pygments syntax highlighting for highlighting of Jupyter QtConsole, Jupyter Console, and Notebook outputs in HTML and PDF format.
- Restore PDF graph support. Although it doesn't display within the Jupyter Notebook for security (or maybe just practical) reasons, it's helpful when exporting a Notebook to a PDF via LaTeX.
- Temporarily fix encoding error from CJK characters being split by a line break. 167

- Fix use of `which` in install script
- Redirect `xstata` to `stata` on Linux. 149
- Fix hiding code lines when there are hard tab characters (`\t`). 153
- Make HTML help links open in new tab. 158
- Open log files with utf-8 encoding. https://github.com/kylebarron/language-stata/issues/98

- Fix pypi upload. Need to use `python setup.py sdist bdist_wheel` and not `python setup.py sdist bdist`. The latter creates two source packages, and only one source package can ever be uploaded to Pypi per release.

- Fix `install.py`; previously it had unmatched `{` and `}`
- Fix display of whitespace when entire result is whitespace. 111
