`exclude` spec does not match the official TS 2.0 spec

[giladgray]

from https://github.com/TypeStrong/atom-typescript/blob/master/docs/tsconfig.md#options:

To exclude directories or files from being referenced. This accepts files or folders. This does not accept glob formatting.

---

from https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#examples:

glob support for exclude:

"include": [
    "src/**/*"
],
"exclude": [
    "node_modules",
    "**/*.spec.ts"
]

can we please reconcile this? really causing issues with TypeScript 2.0 projects...
