Title: `MD_EXTENSIONS` should be a list not a tuple.

If you set `MD_EXTENSIONS` in your config file as a tuple, it throws an error, eg:

```python
MD_EXTENSIONS = (
'codehilite',
'toc',
'extra',
)
```

It should be a list:

```python
MD_EXTENSIONS =
'codehilite',
'toc',
'extra',
]
```

Updated docs to reflect that.
