Markdown support with code formatting

[kakasuarez]

Added code highlighting and markdown support to the question body and answers.

However, normal links inside the body will not work now. Instead they will have to be added in markdown syntax.

This requires the Python-Markdown package.

The language should be added when starting the code block. Like this: ```python
print("hello")
```

I realized, it may not be the best idea to load the markdown_styles.css file in the base.html file. Maybe it should be added only to the specific pages where code formatting is required.

Hi! Sorry about the delay again. I'm actually trying to figure out a way to spend more time on this project although I'm not sure if I'll be able to... I'll keep you updated, anyway.
