New dialyzer output format breaks editors auto-search

[jlouis]

FYI, the new format for dialyzer output:

_build/default/lib/dht/src/dht_refresh.erl
  16: Invalid type specification for function dht_refresh:range/1. The success typing is ({_,_,_}) -> 'ok'
  21: The pattern {'nodes', _, _Token, Nodes} can never match the type {'error',_}
  22: The created fun has no local return
  31: Call to missing or unexported function dht_net:ping/2

Thwarts editor support in many editors. Most editors understand the notion of _build/default/lib/dht/src/dht_refresh.erl:16 and can scan+jump to such errors automatically. The new format has no such direct support and every editor now has to employ helpers for the rebar3 output to achieve the same. This is unnecessary work, so this issue exist to make sure there is an option to disable the new output and get the old output format which has editor-search-support.

Perhaps TERM=dumb should fully revert to the 'old' format?
Other then that the _build/default/18.1.dialyzer_warnings will contain the old warnings so a simple (but ugly?) alternative would be rebar3 dialyzer; cat _build/default/18.1.dialyzer_warnings

I think we should be able to turn all things like this off.
