1. Add selectedFile()/selectedFolder() extension getter methods to MaterialDialog for use with file/folder chooser dialogs.
2. Action buttons now have a 48dp touch target height, still 32dp visibly.
3. Add allowEmpty parameter for input dialogs, which when set to true, allows input dialogs to be submitted with no input.
4. File/folder choosers are smarter about file accessibility, e.g. if your app does not have permission to see files in a folder, that folder will not be considered a parent that you can navigate to.
5. Color chooser dialog cleanup and fixes - which should also hopefully resolve a stack overflow exception.
