- Redirected stderr on HMM check call.
- ``LORAX_INSTANCE_DIR`` environmental variable allows overriding the location of the instance
configuration file. Useful for installations where the default instance path is not
writable by the user.
- ``config_value`` with no arguments now indicates whether variables are set from instance
config files or environmental variables.
- ``config_value --verbose VAR`` gives verbose information about the type of the variable
and where it was set.
- The default type for ``config_value`` is now, in priority order:
* The type specified with the ``--vartype`` option, if it exists.
* The type of the extant variable.
* str if not previously defined and ``--vartype`` is not specified.
- ``config_value --type`` renamed to ``--vartype``, and now accepts any valid python type
for its argument. Types other than str and bool are parsed via JSON and have JSON
typing rules (including demanding use of double quotes in places). Note that for
complex types, you may have to enclose the argument in single quotes to keep the
shell from mangling it.
- `config_value VAR` now prints the value.
