• Heroku support.

• Migrated from SQLite -> PostgreSQL to add support for heroku-postgresql add-on, and to prevent the feed database from being deleted on every redeploy & dyno restart since heroku uses a ephemeral filesystem.

• Implemented better handling of feed items which solves this issue.

• Added a filter to prevent unauthorized access to the bot. Only the Bot Owner can now use the commands.

• Added three new commands, /template, /unsuball & /get.
