Title: Coordinates subpackage

This is the long-awaited `astropy.coordinates` package. You can look at the sphinx docs this generates at http://eteq.github.com/astropy/coordinates/index.html . All the tests passed (at least for me locally - we'll see what Travis says).

There are a variety of enhancements, including:

* Expanding the range of coordinate systems to include a proper ICRS -> CIRS -> TIRS conversion chain.
* add a `Site` object to allow a way to get `HorizontalCoordinates` from othere kinds of celestial coordinates (and vice versa)
* supporting arrays
* supporting uncertainties

All of these are goals for 0.3, though - once this is merged, I can add issues for them.
