Make --show-iface more human readable
Right now --show-iface is not particularly interpretable, even if you are looking at the Outputable instance for ModIface. The problem seems to be the output for mi_deps, mi_usages, mi_decls, mi_insts, mi_fam_insts and mi_rules is not clearly delimited, making it unclear (for example) what import -/ base:Prelude HASH refers to unless you already happen to know that this must be from mi_usages.
It should be relatively easy to improve this, but I want to make sure people who rely on this output aren't blindsided by the changes.
