Add part_of relationship option for query of fascicles in VNC

[fewtrem]

I want to be able to see the children of general fascicle classes e.g. A: http://www.virtualflybrain.org/site/stacks/index.htm?id=FBbt_00005903 will give B: http://www.virtualflybrain.org/site/stacks/index.htm?id=FBbt_00111638

but there is not a button for this in A's queries.

Checked on sandbox and not able to do it on there either
