Makes log record propagation a bit saner

I don't understand how this is not a Python bug, but the users seem
happy about this. It is terrible.
Makes LevelCheckerLogger instanciation safer
Prevents "no handlers for logger "root"" warning
Renames debug's logger VisLog -> vistrails
Different approach -- two loggers

The logger that the 'debug' module logs on is now vistrails.logger. It
is internal and API users should NOT configure it (change level or
attach filters/handlers to it). It is controlled by the 'debug' module.

This internal logger re-logs to a 'vistrails' logger, which is meant to
be configured by API users if needed -- changing the level of this one
won't break anything.
Importing debug no longer adds a console handler

This means that a root logger should either be configured (usually the
case when VisTrails is used by something else) or log_to_console()
should be called to add the console StreamHandler to the root logger.
Makes set_message_level() change 'vistrails' level
Removes EigenPipelineSimilarity
Removes untitled_locator()
Removes CachedInterpreter#_executed
Removes BaseMonitor
Removes some unused locals
Removes OutputModeConfig#get_local_fields()
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"
Merge branch 'remove-dead-code' into 'master'
Updated VisTrails Server for rewrite-startup

vistrails/core/configuration.py:
  Added server flags back. There are now no single-letter versions.
  Added descriptions for server and job sections.

scripts/start_vistrails.sh:
  Use new flags

scripts/start_vistrails_xvfb.sh:
  Use new flags

vistrails/gui/application_server.py:
  Use new flags and propagate argv

vistrails/vistrails_server.py:
  Use new flags and propagate argv

doc/usersguide/batch.rst:
  Updated flags and ../examples path
  The table is still out-of-date
Fixes NameError in basic_modules.py
Merge branch 'logger-propagation' into 'master'
Removes __import__ madness
