[Typo3-dev] MM relationships both ways

[dan frost]

FYI

Ok, i've done my XCLASS version of this and it requires a few steps:

1. checking the config for an alternative (e.g. isset($config[...]))
2. making *all* calls to ->start(...) pass the full config - otherwise 
there's no sensible way of getting the config for #1
