Allow Array type for generic types.

There are two interferring TSLint rules:
 - array-type (TSLint built-in)
 - prefer-array-literal (tslint-microsoft-contrib)

For now:
Valid types:
 - `string[]`
 - `SomeType[]`
 - `Array<GenericType<string>>`

Invalid types:
 - `Array<string>`
 - `Array<SomeType>`
 - `GenericType<string>[]`
