#5041: make it so the magma .sig files in extcode don't get written there by 
magma
------------------------+---------------------------------------------------
 Reporter:  was         |       Owner:  was     
     Type:  defect      |      Status:  new     
 Priority:  blocker     |   Milestone:  sage-3.3
Component:  interfaces  |    Keywords:          
------------------------+---------------------------------------------------
 If one installs sage sytem wide, and a user tries to run any magma
 commands, and the .sig files aren't written in data/extcode/magma, then
 BOOM!  This is a total show stopper for any "normal users" to use the sage
 magma interface for anything serious.  This must be FIXED!

 To fix this, when the magma interface is first run, make sure to copy the
 .m files over to $DOT_SAGE/magma first and load from there.   One will
 have to do the copy the first time the magma interface is started in any
 magma session.   alternatively, one could try: except: the magma.load
 command, and if it fails, then try to copy and load from /tmp/, say or
 DOT_SAGE/temp/.  Maybe the second idea is cleaner.
