create implication two_doms_one_sub (2362) -> multiple_doms_one_sub (510)

create implication two_doms_one_sub (2362) -> threesome (66527)
create implication two_subs_one_dom (1401) -> threesome (66527)
create implication multiple_doms_one_sub (510) -> dominant (181712)
create implication multiple_doms_one_sub (510) -> submissive (163059)
create implication multiple_subs_one_dom (151) -> dominant (181712)
create implication multiple_subs_one_dom (151) -> submissive (163059)
Reason: Hopefully self-explanatory. The only issue I foresee is that multiple_*_one_* ought to imply group, but that can't be done if two_*_one_* implies multiple_*_one_* without mistagging a lot of trio images as group.
If it is preferred to keep multiple_*_one_* separate, may I suggest changing the name to many_*_one_* to make it clearer that it's not a superset of two_*_one_*?
