Workout Library Part 1 of 3

Implementing a workout library that keeps
track of media and workouts that can be used
in train view.

This first part implements;
- library.xml to record search paths
- search dialog to find media/workouts

Part 2 and 3 will bring:
- Sqllite libraryDB to store found details
- Update traintool to use libraryDB and display
  icons, duration/distance, IF and TSS in list
- import and drag-n-drop of new media/workouts
