Changed documentation theme. Now using the kr theme by @kennethreitz which is based on the Flask project theme. Remade documentation with new theme.
Removed old, now redundant .hgignore and replaced with the standard .gitignore for Python (from GitHub). Added build and dist directories to ignore file.
docs/ directory deleted and .gitignore updated. The reason for keeping a version of the documentation built as HTML was that this project was previously hosted on Google Code, where a link could be created to the live docs. Now that the documentation for this project is hosted on readthedocs.org, where the docs will be built on the cloud, there is no need to keep documentation in the repository, where it can become deprecated.
