Request: Namespace/Domains and Certs for MITs

[CaptainStevey]

Can domains be introduced for MITs? I'm unsure what level of usage is expected by MVS for MITs, but if many users start to use MITs then you may have problems with fraudulent MITs and MIT squatting. For example:

If you were to create community token awards to show appreciation for the community, the MIT names could be:

MVSCommunity.BestHaircut MVSCommunity.MostLikelyToCreateGITHUBRequests

However, without a domain feature like we have with MSTs then someone else could come in and create negative awards and squat others:

MVSCommunity.WorstCoder MVSCommunity.ChenHao

The domain feature was an excellent idea for MSTs and should be applied to MITs too.

Maybe we can extend the scope of the existing domain certificates to also affect the MIT namespace instead of creating new certificate types? @CaptainStevey @betachen @LaurentSalou

This feature definitely requires a hardfork because the MIT transaction rules only allow MIT outputs if there is no other output other than ETP or messages
