Debug output not printed/stored when running BART with Python

[mavel101]

Hi,

since commit 10d2df3, the debug output in BART is sent to stderr instead of stdout.
This is not captured by the Python wrapper though, since stderr is only written in case of an error - see bart.py lines 193-198:

  # in case of error, print to stderr
  errcode = proc.wait()
  if errcode:
      stderr = "".join(proc.stderr.readlines())
      print(stderr)
  proc.stderr.close()

Probably the if statement should be removed here, or maybe one could check if the debug flag is set.
