Choose Folder Option

[nielsdebruin]

This PR adds the ability to select folders.

Usage

The user can create a new folder chooser using either:

• new MaterialFilePicker().withChooseFolderMode(true)

• intent.putExtra(FilePickerActivity.ARG_CHOOSE_FOLDER_MODE, true);

When choose folder mode is enabled a floating action button will pop up. Pressing the button will select the currently opened folder.

@lukaville, @dimorinny: There are news?

Is there any update on this? I'm hoping to build a React native app that builds on top of this
