Title: Update code to use SkyCoord everywhere

We should consistenly use [SkyCoord](http://astropy.readthedocs.org/en/latest/api/astropy.coordinates.SkyCoord.html) instead of the older `ICRS`, `Galactic`, ...

Caveat: a lot of gammapy functions take pixel coordinates as input / output, and there is no astropy class representing those yet!
