Add dot component files to documentjs config ~1

@Macrofig commented on [Wed Aug 24 2016](https://github.com/donejs/generator-donejs/issues/142)

The generator currently creates the following `documentjs.json`

``` json
{
"sites": {
"docs": {
"dest": "docs",
"parent": "bithub-admin",
"pageConfig": {
"page": "docs"
},
"glob": {
"pattern": "src/**/*.{js,md}"
}
}
}
}
```

This does not document `.component` files.

Should output the following:

``` json
{
"sites": {
"docs": {
"dest": "docs",
"parent": "bithub-admin",
"pageConfig": {
"page": "docs"
},
"glob": {
"pattern": "src/**/*.{js,md,component}"
}
}
}
}

```

Do you document .component files?
