Proposals
- rename config2.py to config.py and implement loading all global and user-defined settings
- global bot settings can be located in pywikibot/config.ini
- userdefined settings can be located in user-config.ini
- script related settings including L10N can be located in scripts_config.ini
- drop user-config.py support. This might be a great advantage using PAWS
- enable site-related settings e.g. from wiki page
