Refactor: Create database connection without Laravel's app() helper

[minthemiddle]

• It would be great if you could bear_sync without Laravel
• The only problem so far is app() (BearNote.php, l.54) which throws an undefined function()
• One idea on the how can be found in this gist
• (I will try to create a PR for this)

Yeah, that should do, I'd like to resolve ConnectionFactory out of the container for Laravel apps, so maybe a conditional that checks if "app()" is defined and uses the strategy you referenced if it's not? Looks good to me though.
