Various small fixes

* 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
