v0.3.1

Minor Enhancements

• Add short versions of --log-level, --conf and --version, -l, -c and -v.
• Add -s --skip-external option. Disables CheckExternal, rather useful when running locally and calling many times.
• Combine config options and command line arguments. CL arguments take presidence over config file options.
• Improve error message when config file is specified but not found
• Dump resolved options to output when debug enabled.

Bug Fixes

• Fix issue where specifying --log-level would cause certain crashes.
