Finish RecordFABView

[bajabob]

pull from develop first and don't forget to do this work under a feature branch called feature/67-record-fab-view

As a developer of the Fast Phrase application, my job is to create a floating action button (FAB) for the playback list activity view. This button is to hover over the scrolling list and open the RecordingActivity when pressed. The button must match the styling in the render below. All shadows, colors, lines, etc. Additionally, when the FAB is pressed it must show a ripple effect across its surface (like the ripple seen when touching folders). Ensure to the Listener!

As a developer I also need to implement the following methods:

• onFadeOut() - when called this method will make the button fade away permanently until fade in is called.
• onFadeIn() - when called this method will make the button fade in

Colors (see res/values/colors.xml): Background red: ra400 Outline red stroke: r900

Files you'll be poking around in: views/RecordFABView.java and res/layout/view_record_fab.xml.

FAB exhibits interesting (and unwanted) margins when used with < API 21.
