Prior to this commit, the file commitmentlist, which stores
commitments (podle) for makers to let them blacklist/prevent
reuse was stored in the local directory for the script, which
allowed remote running of jmdaemon but was very unhelpful for
any situation where multiple bots are running at once, e.g.
in testing or using multiple wallets against the same codebase.
This could result in incorrect rejection of coinjoins.
After this commit, by default, the commitmentlist file is stored
in datadir/cmtdata/commitmentlist, so it will be local to any
custom data directory as would be the case for running multiple
wallets on the same machine. A user can set the POLICY variable
commitment_list_location to "." to revert to the previous behaviour.
