Close low hanging fruit PRs before SDK v7 refactors begin

[theethernaut]

Before we begin doing heavy refactors for SDK v7, we want to assimilate PRs that:

• Are simple enough
• Are compatible with the general direction of the upcoming refactors
• Don't add feature / complexity
• Have value and would be too complicated to include after the refactors have been implemented

PRs included:

• Import ABIs from @aragon/os and @aragon/id, to resolve #818 #833 or Removes hardcoded contract ABIs #837
• Displays version on debug = true #839
• getTransactionPath refactor #840
• help user with next steps, to resolve #831 #841
• Show a detailed error with next steps when cyclic dependencies are found, to resolve #780 #844 Truffle flattener cyclic dependencies error - re-work on PR #844 #857
• Detect if IPFS is initialized in a more robust way, to resolve #744 #845 (postponed)

@macor161 I wasn't able to assign you to this issue, not sure why... could you add yourself please?

#845 doesn't seem to be working well. I propose we postpone it until after the refactoring is done.
