Update SCons to latest checkpoint release, 1.2.0.d20090113....

 """SCons.Script
 
 This file implements the main() function used by the scons script.
 
 Architecturally, this *is* the scons script, and will likely only be
 called from the external "scons" wrapper.  Consequently, anything here
 should not be, or be considered, part of the build engine.  If it's
 something that we expect other software to want to use, it should go in
 some other module.  If it's specific to the "scons" script invocation,
 it goes here.
