After some discussion about the patch in 
http://bugs.freepascal.org/view.php?id=21990 the main question to remain 
was: treeview or grid

The main reason for treeview (as far as I am aware) was/is, that 
additional future feature may be easier to be implemented.
But they are not implemented yet. If someone is indeed picking up work 
on such features, then we can look at bringing the treeview back in 
(until the grid can do it too).

For now I have done the following. (r 37259)
- For none structured long values (strings) currently a memo with 
word-wrap is better(better than treeview or grid)
   Allows displaying long text.
   Allows copy, copy selection
- Same for memory dumps, until we have a nice viewer for mem dumps
- For structured values:
   The plan is still the grid, including extending the grid for sub-nodes
   Until the grid (or rather the persistent storage system) has at least 
auto-size columns, the memo is used too, but without word wrap.
   The data is cleaned up (methods on a single line)

I added the splitter to the persistent storage (not supported by 
docking) so it's width will be remembered.

I added a tool-button to toggle the entire inspect pane
- the button state is not yet persistent
- the icon is actually the icon for the stand alone inspector window. It 
would be nice to free it up, so we can have a button to sent a watch to 
the stand alone inspector win. But I am no gfx expert. If someone has an 
idea...
