Incorrect kbd directory when running key-mon inside PuDB

[GoogleCodeExporter]

Case #1 - works correctly:
$ cd src
$ ./key-mon

Case #2 - fails:
$ cd src
$ python -m pudb.run ./key-mon

IOError: [Errno 2] No such file or directory: './keymon/./keymon/us.kbd'

This exception raises from mod_mapper.read_kdb():
  return parse_kdb(codecs.open(os.path.join(os.path.dirname(__file__), fname), 'r', 'utf-8').read())

Replacing fname with os.path.basename(fname) solves this issue, but I don't 
know if it breaks anything else. (I've done that as a quick-and-dirty fix just 
for debugging inside PuDB)

Reproduced with hg revision 299:0bb208c4c367

PuDB is available at:
http://pypi.python.org/pypi/pudb

Okay, I did a bit more of debugging... I found this bug does not happen if you 
have an empty config file.

I've tracked down the bug to keymon.settings.get_config_dirs() function. It 
uses __file__ to find out what is the directory. When running standalone, 
__file__ contains the absolute file path. However, for some reason that I don't 
know yet, when running inside PuDB it contains './keymon/settings.pyc'.

The fix should be easy: os.path.abspath(__file__)

According to this mail thread:
http://mail.python.org/pipermail/python-dev/2010-February/097461.html
__file__ will be absolute or relative depending on the values of sys.path

(okay, this comment doesn't help fixing this issue, it's just nice to 
understand how things work)
