Update requirements
While working with Markdown extensions (c.f. #74), I noticed that mkdocs' setup.py has its dependencies [pinned to specific patch versions](https://github.com/tomchristie/mkdocs/blob/master/setup.py#L18):

```
install_requires = [
    'Jinja2==2.7.1',
    'Markdown==2.3.1',
    'PyYAML==3.10',
    'watchdog==0.7.0',
    'ghp-import==0.4.1'
]
```

Since these dependencies are slightly out of date (e.g., [Jinja2 is at 2.7.3](https://pypi.python.org/pypi/Jinja2) and [Markdown is at 2.4.1](https://pypi.python.org/pypi/Markdown)), it's hard to use mkdocs on a system with other software. Perhaps it's a shame that Python doesn't have npm-like dependency management, but that's the way it is—you'll get a setuptools when trying to run mkdocs error if any other package upgrades Jinja to a bugfix release.

How would the developers feel about loosening these version requirements? An idiomatic approach is to [just use `>=`](https://github.com/mitsuhiko/flask/blob/master/setup.py#L99).
