Proper sql logging

Use filter

Reduce arguments.length lookup when not necessary

Refactor all internal .query calls to use .query(sql, options); instead of .query(sql, callee, options)

The callee is now passed to .query by using `options.instance = callee;`

Fix condition in model wide validation

Foreign languages used in the db might crash the app

Update associations.md

spelling

Update model.js

Fixed typo

Reduce chai use

Return sequelize instance / dao after .sync and use promise.each instead...
