v1.17.0

Added:

• Ability to .save() bot.conf - we now use only this for module whitelist/blacklist
• A cron system (src/core_modules/cron.py)
• healthcheck.py - ping a URL every 10 minutes (for uptime-tracking services)
• Support ++nickname style karma (karma.py)
• Bot-wide aliases (!balias in aliases.py)
• Support per-user (PM) command-method setting (commands)
• dnsbl module to loop up given IPv4 and IPv6 addresses in blacklists

Changed:

• "Core" modules (modules needed for base operation of bitbot) moved to src/core_modules and made blacklist-immune
• Better parsing error for !config u birthday (birthday.py)
• Show display name, not username, when available (fediverse.py)
• By default, show locked/unlocked github issue/PR events (git_webhooks)
• Switch back to full wolframalpha API but use it better than we used to (wolframalpha.py)
• Hostmasks are now precompiled to find users that match them (permissions)

Removed:

• -m/-M args to bitbotd - didn't work any more due to databse locking
• database_backup.py - this was always a weird hack. Added a note about backups in README.md
