[FIX JENKINS-10536] Package Groovy DSL descriptor for eclipse in core jar to ease creation of groovy views in eclipse

talks about the border conflict resolution specified in

What this fix does is to set the cell-level right border for pane
tables. I realize that this might break table nesting inside another
table.
