Should support tslint "trailing-comma" rule

[Maximaximum]

When trailing-comma is set to false,

export enum CompanyType {
    Customer = 1,
    Supplier = 2,
    FreightAgent = 3,
    None = -1,
}

should get converted to

export enum CompanyType {
    Customer = 1,
    Supplier = 2,
    FreightAgent = 3,
    None = -1
}

same as #127 I recommend you to use tslint --fix. Do you try it already?
