Even if the variable is not used and the linter might complain we have
to have that parameter in the signature. otherwise the method is not
found and can not be called.
This removes the isCore flag and allows us to dynamically calculate the
core flag for contributors.
For now this is just us (the first 6 contirbutors)
Also we do not need the default contributor anymore because the deploy
user has the role to manage contributors and can create the first real
contributors.
It seems that the entity is either defined by the permission or if we
want to use the oracle the permission must be defined for any_entity.
In that case the oracle does not get the msg.sender as who/entity thus
we will use tx.origin in that case.
AppIds are used to lookup the actual contract addresses of each app.
Because of different registry names (open.aragonpm.eth vs. aragonpm.eth)
we have to use different ids in the local dev chain and in the
testnet/mainnet. To allow this we need to set the appids dynamically.
There is an open aragon issue to solve this and also allow to use
open.aragonpm.eth in the devchain by default.
