#340: Improve error message when parameter file is not found

     Type:  defect      |      Status:  new    
 Priority:  minor       |   Milestone:         
Component:  SimFactory  |     Version:         
 Keywords:              |  
------------------------+---------------------------------------------------
 I specified a wrong path "par/recover.par" for a parameter file, and
 Simfactory didn't find the parameter file. Simfactory's error message was:

 Error: specified parfile /project/numrel/eschnett/philip/EinsteinToolkit-
 hg/simfactory/etc/parfiles/par/recover.par does not exist or is not
 readable

 This is confusing, since the parameter file was not in the "parfiles"
 directory of Simfactory. Simfactory should list all the places where it
 looked for a parameter file, and should also output what the user actually
 specified.
