Add configuration. See #5 #8.

What's new:
- --config flag to pass a INI config file to parse. See config.ini.
- Updated the modules scripts for configuration. Now needs to unset
  variables passed by CLI or config.
- Fix release directory that was added in love file (maybe).
- Properly escapes sed arguments.
- chmod +x to getopt.sh and read_ini.sh
- Fix #12
