Few issues

[Former user]

Hi Nick, Few issues which you may want to fix ;)

• The doc says its default SQLite but that's not true, it's postgressql
• You may want to link to the user doc at https://docs.arijea.com/moodapp/using-moodapp/
• When doing rake db:migrate it spits out an error when making an admin because there are no users, but if you create an user then you need to re run the db:migrate since there are more things that a required for the database to be complete
• I also get an error about RollBar (Over plan monthly limit), i don't know what i am missing without this. It seems to work but maybe there is something i can't see.
