Ansgar Becker 3f0b70c409 Switch ListColumns from TSortListView to TVirtualStringTree ...

Additionally/Sideeffects:
- Fix vstFreeNode to delete the item from the array, not only free the item itself
- Change/Rename GetSelectedNodesFromVT to GetVTCaptions and give it the ability to return all captions, not only the selected. This function is very useful now and saves writing much redundant code.

A table with 500 columns needed 3 seconds to display in the TSortListView, now that takes less than a half second.
