[Squirrel-sql-develop] needed fixes

Hi,

i encountered a couple of things that should be fixed in the latest cvs release.

1> 
if varchar > 50 then i set the lenght and append "..."
this should not be done anymore in the ResultSetDataSet but thould be done
with a Renderer in a IDataSetViewer implementation
So that when you double click on it you will get all the text in the popup textarea

2>
If you do a refresh on a tree then the the cursor doesn't go to normal anymore (stays in wait)

3>
The tree will be expanded with all the children are loaded before (so not really yhe expanded
state but the complete state of all the nodes that are onces expanded.
To go around this is a bit difficult at them moment.
