add switches for bot services

[socphoenix]

Add table to config.py to store if the community wants to only use certain parts of the bot

• [x] default prompt for all services
  • [x] individual prompts for services
• [x] add if blocks to check with database before running scripts on schedule.

Users upgrading will be notified with stdout that without running config.py again the bot will assume it should do all of the posts it is capable of.
