UI: Drag&Drop: Configuration

Implement a possibility to apply special options for a component.
In order to be used in another application, it should have good configuration possibilities.

Options:

• multiple uploads
• wrapper class
• restricted file formats
• show progress: true / false
• drop overlay zone (when user drag a file to a page)

All information and error messages should be configurable via translation (same as common stripes components approach).

Note: SHould be revied by another team if it fits their requirements.
