brace-style doesn't work for classes

The rule brace-style does not affect the braces around the class body – see the fixed bug at eslint/eslint#7608.

How to reproduce

/* tslint brace-style: ["error", "allman"] */

class Foo {
}

Expected

• tslint throws an error
• if I change the code to Allman, it should be ok

Actual

• no error was thrown
• if I change the code to Allman, tslint throws an error

I haven't done a PR because I couldn't find the Typescript API specs, but it should be relatively easy to fix. If I understand it correctly, we need to add something like this to the rule definition:

visitClassDeclaration(node: ts.ClassDeclaration) {
   let block = somehowGetTheBlock(node);
   this.visitBlock(block);
}

visitClassExpression(node: ts.ClassExpression) {
   let block = somehowGetTheBlock(node);
   this.visitBlock(block);
}
