Altered DropDown widget (#60)

* Altered DropDown widget: Added another mandatory path variable - selection value (depending on use case, one could prefer direct access to selection value rather than selection index); and another optional path variable - options (string variable to allow for dynamic change of options, as opposed to providing static list of options through arguments); and example with both static and dynamic dropdowns.

* Make second path variable optional, for backwards compatibility

Button widget takes one boolean variable path, and reflect current true
or false value by showing "active" or "inactive" labeled element
respectively. Clicking or touching button toggles variable.
