Alternate color on tree

[hilaire]

The items in the tree structure in the left part of the DrGeo window are not right
The background of the items should alternate with white and gray. Now it is only white.

Yes, I do remember this when pharo launcher changed to use pharo 5.
Some code for setting the secondary color was removed in initialization.
Maybe because it wasn't theme aware.

possible fix:

DrGTreeMorph

initialize
 "initialize the state of the receiver"
 super initialize.

 rowColors := Array
  with: self theme backgroundColor lighter
  with: self theme backgroundColor darker.

It is a fix!
