Initialization should conform with other adapters

[ekryski]

All other db adapters support these options:

• Model (required) - The knex object scoped to a table
• id (default: id) [optional] - The name of the id property
• paginate [optional] - A pagination object containing a default and max page size (see below)

So it should look like this:

var knex = require('knex');
var knexService = require('feathers-knex');

app.use('/todos', knexService({
  Model: knex('todos')
}));

We needed to add the name attribute to this adapter because of the way that knex queries work. If you don't make a call to knex('table_name') every time then you end up with weird results. An alternative is to use the .from('table_name') syntax but you'd still need to call it every time you make a query.
