CustomDialog.Builder without captions

I needed to create single instance of CustomDialog.Builder though app, and then use it everywhere, and still be able to customize stuff.

now i use it like that
```
@Provides
CustomDialog.Builder provideLDialogBuilder(@ActivityContext Context context) {
  return new CustomDialog.Builder(context).typeface(...).contentTextSize(...);
}
...
@Inject CustomDialog.Builder dialogBuilder;
....
dialogBuilder.build(getString(...), getString(...)).show();
```

it makes much more sense now. If u think its fits your lib, i'll add same things for ListDialog and add docs/fix readme in this request
