create alias solo_gynomorph (3) -> gynomorph (5098)

create alias solo_humanoid (0) -> humanoid (6078)
create alias solo_feral (0) -> feral (24499)
create alias solo_taur (0) -> taur (376)
create alias solo_cuntboy (0) -> andromorph (475)
create alias solo_dickgirl (0) -> gynomorph (5098)

Reason: The purpose of these tags is the same as just having solo + gynomorph and so on, making these redundant.

Aliases for solo_male -> male and solo_female -> female are already currently active on e6ai at alias #6481 and alias #9560 so these match that same standard.

EDIT: Added solo_cuntboy and solo_dickgirl.

EDIT: The bulk update request #773 (forum #5062) has been approved by @Jelloponies.
