Better document parameters of integrators, esp. dop853 (e.g., tunable accuracy) #215

As reported by @eugvas via email

Initial note:

Are there any tunable accuracy parameters for the dop853 orbit integrator? I find that it has a rather poor energy conservation accuracy by default (although by no means abysmal, just prevents a fair comparison between orbit integration routines from agama and gala).

But then:

this has now been resolved - apparently the scipy version has a fairly lousy default tolerance of 1e-3, instead of 1e-10 in the cython version

The documentation or at least the docstring should clearly note this.
