[Qgis-developer] Recent changes to legend

Being the culprit behind r5594, I'd better add some commentary...

As per my commit message:

"QGIS used to do this already before the move to Qt4 - however the new
QIcon idiom only seems to allow for square icons, therefore it is easier
to split the results out to several columns and give them their own
QIcons."

Each QTreeWidgetItem only appears to allow for 1 icon and 1 piece of
text per column, therefore I can't see how you can just append more
icons without also appending more columns...?

Also, I added the column headers back in because then you can at least
resize the columns yourselves if your layer names are long.

As for layout, are we *really* that scared of a horizontal scroll bar?
Or have I missed something?

Thanks for the feedback, anyway.  I'm finding it's a dance between what
the users want vs. what Qt4 can give.
