Added back running vistrail in db from command line

This also adds back the "parameters" flag and removes temp_db code

core/configuration.py:
  New conf options parameters,host,port,db,user

Use conf and not temp_db in:
  core/application.py
  gui/application.py
Fixed control_parameter typo in translating 1.0.4->1.0.3

db/versions/v1_0_3/translate/v1_0_4.py:
  Should have used "controlParameter"
