Inscriptis

- improved indentation, if span and div tags are used
- support for custom rendering styles
- improved documentation
- use travis for auto CI
- requires Python 2.7+ or Python 3.5+ since lxml does not support Python 3 versions <3.5

* Correctly handle nested tables and line breaks (e.g. due to enumerations, list or paragraph breaks) in tables.
* Improved content stripping.

Please take a look at the [Rendering](https://github.com/weblyzard/inscriptis/blob/master/RENDERING.md) document for an overview of how Inscriptis renders different tables.

* use requests for URL fetching (this addresses 17 and prevents `403` responses with some Web servers).

* correctly parse negative margins in CSS definitions.
* This fixes a bug that led for some pages to a high number (>1000) of newlines between content.

This prevents encoding errors when using `inscript.py` for converting HTML pages to text.

Decode HTML entities such as `Auml;`, `Ouml;`, `Uuml;`prior to returning the plain text version of the HTML page.
