Dynamically get app ids from the namehash

Browse Source 
This dynamically hashes the app id which makes it easier to manually set
contract addresses. This is useful in development environments with no
default network ids.
The used apm (which is part of the app id hash) is configurable.

usage:

new Kredits(provider, signer, { addresses: { Kernel: '0x...' }, apm: 'aragonpm.eth' })
