Allow multi-selection when delete multiple variables from a table

[GoogleCodeExporter]

for example, right now it is a real pain to “delete” multiple variables 
from a table. the UI is all set up for just a single variable. two things are 
wrong for when you have multiple variables: 
 - the variable list goes back to the top and does not stay with the last selected variable (since that one has disappeared from the list,  I assume the default is to go back to the top), that means you have  to scroll all the way back down to where you were - there is no way to select multiple variables (e.g., with shift-click or
  command-click).

Fix: using list box to replace a drop-down choice box for multi-selection of 
variables. Users can hold Cmd (mac) or Ctrl (wiin) to select more than 1 
variables to delete.

This fix has been applied in versions >= 1.7.31
