META updates, tidy, PBP tweaks

* update manifest
* move user_config $rc test into block that could set it
* perltidy
* replace postfix if/unless with brackets
* reduce useless indention by exiting sooner
* bump version
Is this supposed to be 'next PLUGIN_DIR'?  Or is the PLUGIN_DIR block even useful for anything except confusing me about whether or not it's supposed to be referenced in 'next' and 'last' statements?
