squirting_dildo implication + utility alias

BUR #35827 has been approved by @evazion.

create implication squirting_dildo -> dildo
create alias ejaculating_dildo -> squirting_dildo

"Ejaculating dildo" is a less common but still popular term for this object. The implication should be self-explanatory.

Oh, so that's what normal people call it.
For whatever reason, furries name it "cum tube", so I had a bit of trouble finding it.
