Repository: mui/material-ui (TypeScript) — Feature

Issue:
typescript definitions not available on root of @material-ui/core
Why can I do:

```ts
import { IconButton } from '@material-ui/core'
```

but not:

```ts
import { IconButtonProps } from '@material-ui/core'
```

instead I have to do

```ts
import { IconButtonProps } from '@material-ui/core/IconButton'
```

It would be much more consistent if types were exported in the same places as their associated components.
