Enhance Wave Reference Wave Browser for nD waves

- add context menu on wave reference waves in data browser
- add context menu for columns in tables to open WRB
- add preview of the first 10 points in the sub wave
- add attached subwindow that shows the current waveref wave in a table

The table allows to navigate on multidimensional waves and to browse
further. Due to Igor Pro limitations the workflow is like:

On tooltip popup the marked element is moved.
Press enter to open the last wave reference wave where a tooltip was
last shown. (The marked element is for visualization only)
