A Bookshelf plugin that adds model.upsert()

$ npm install --save bookshelf-upsert

const upsert = require('bookshelf-upsert')

bookshelf.plugin(upsert)

const model = require('a-bookshelf-model')

model.forge({ some: 'data' })
.where({ optional: 'constraint' })
.upsert({ optional: 'attributes' })

Bookshelf model instances are provided the upsert method, which may optionally be given attributes to save. The attributes are simply passed along to model.save(). This implementation of upsert first attempts an update then if no rows are updated it follows up with an insert.
