Fluent 1.2.0

New:

• Adds custom data types.
• Adds unique fields.
• Adds default values for fields.

A sample of new field APIs being used:

static func prepare(database: Database) throws {
    try database.create("users") { users in
        users.id()
        users.string("name", unique: true)
        users.custom("data", type: "JSON")
        users.custom("time", type: "TIMESTAMP", default: 1234)
    }
}
