Db

Simplified testing by removing boilerplate (setUp function), just subclass TestCase from __init__.

Added flask-testing for testing utilities

Added database module (sql-alchemy). The db location might not be ideal.

Added user model, views and templates for login, register, dashboard and logout

Added error pages,

Added utilities file for utilities
Any way to apply to whole project? was missing editorconfig in sublime on one of my machines. 

In case there are some files I missed.
