* Save the fakeplayer's wielded item in set_wielded_item
* pipeworks.luaentity: Return the found objects in get_objects_inside_radius
* Remove the invalid and unused on_blast return values in lua_tube.lua
This should avoid a crash when a strong explosion happens next to a Lua Tube.
* Do not access a global "nodename" in a BUG message.
This avoids a potential crash, in case the message actually appears in practice.
* Set the Flow Sensor and Fountain Head mesecons connection rules
* pipeworks.luaentity: Use the same function for move_to and set_pos
* (no functional change) Do not save the object returned by tube_inject_item into the "item1" local variable in filter-injector.lua
This allows the raw offset to be visible inside that for-loop, which will be needed for calling the directionfn for directional neighbours to determine if they can flow in the given direction.
The "new flow logic" name was supposed to indicate that it was a continuation of the old branch by the same name, but it is beginning to become clear that it's not "new" any more and it might lead to confusion with "classic mode" flow logic while that still co-exists.
Explicitly name the subdirectory "pressure logic" to give a better idea of what goes in it, init.lua edited accordingly.
