Added upvotes and downvotes

Changes:
- Added upvotes and downvotes parsing.
- Added text to read from selftext and selftext_html.
- Added an texttype to imply what type of text is present (HTML or raw text)
- Added some documentation.
- A few minor changes (I hope).

- Removed the pinned field.

Todo:
- Remove texttype field and parse the selftext_html into raw text
