From 31d4280bf3c1c0b24cd586b17c8d34cdb2f09647 Mon Sep 17 00:00:00 2001

Subject: BUG:  Fix behavior of CMakeSetupDialog::set{Binary|Source}Directory  
     so they work right when called externally.       Disable the generate
 button when one hits configure again. ENH:  Some UI tweaks for spacing.      
 Allow viewing cache values while configure/generate (but not edit).
