bufgfix for [#13584] SIGSEV in fluid bake with large amount of small fluid objects
the maximum number of objects (255) wasnt being checked, added a check before baking.
also changed bakeing to use G.scene->base rather then G.main->objects since these can be in other scenes, from linked
groups, or used only by python so they should not be used for baking. it also meant having a domain in 2 scenes would fail with an error.

Nils, could be good to have a dynamic number of bakeable objects.
