Allow bypassing min post length for certain groups or trust levels

Idea: Allow some groups or trust levels or admins to bypass limits such as min post length, min personal message post length, body min entropy, etc.

We’ve found that we like the limits for everybody except our stakeholders, who often want to build the relationship with users by responding with more than just clicking the heart, but all it requires is “Thanks” or “Success!” or something like that. We don’t want to lower the limits that far for everybody else, but apparently(?) there’s no way even for admins to bypass these limits.
