Reload an object using the update method

[MarkusFreitag]

Currently the update method returns a new object, but it should also update itself.

After looking into it further, calling update can be used the update an attribute. So we should introduce an extra reload method.

That would be very useful, right now I do action = hcloud.actions[action.id].

Howdy, i'm actually rewriting the whole code base, i assume this will be fixed soon

I'd be happy to test a pre-release, if that is helpful for you.
