Better loop variable state handling

Browse source 
* Loops caused local scripts variables to be backed up then restored,
    which would have caused a set_var in a loop to have no effect.
  * Instead, we back up the state of the variable (existing or not,
    value) and either restore the original value or delete the variable
    if it didn't exist.
