Minor revision

Changed

• PALEOMIX now uses the 'setproctitle' for better compatibility; installing
  / upgraing PALEOMIX using pip (or equivalent tools) should automatically
  install this dependency.

Fixed

• mapDamage plots should not require indexed BAMs; this fixed missing file
  errors for some makefile configurations.
• Version check for java did now works correctly for OpenJDK JVMs.
• Pressing 'l' or 'L' to list the currently running tasks now correctly
  reports the total runtime of the pipeline, rather than 0s.
• Fixed broken version-check in setup.py breaking on versions of python
  older than than 2.7, preventing meaningful message (patch by beeso018).
• The total runtime is now correctly reported when pressing the 'l' key
  during execution of a pipeline.
• The logger will automatically create the output directory if this does
  not already exist; previously logged messages could cause the pipeline
  to fail, even if these were not in themselves fatal.
• Executables required executables for version checks are now included in
  the prior checks for missing executables, to avoid version-checks failing
  due to missing executables.

Added

• PALEOMIX will attempt to automatically limit the per-process maximum
  number of file-handles used by when invoking Picard tools, in order
  to prevent failures due to exceeding the system limits (ulimit -n).
