Coughing blood implications

BUR #36596 is pending approval.

create implication coughing_blood -> coughing
create implication coughing_blood -> blood

Self-explanatory. It features a person coughing up blood.

There's a lot of overlap between coughing blood and spitting blood. Do we want to alias these or try to keep them separate?

Looks like posts with coughing blood tend to show a character badly injured or ill.
Meanwhile spitting blood is present in posts where a character is spitting blood as if it was saliva or is being punched in a comical scenario.

I think it is worth keeping them separate and maybe properly tag posts to reflect this, since there are not many. Also there is vomiting blood to consider.
