Config file paths are relative to current working directory instead of config file location

These may be windows related. However, two things I ran into so far one small and the other will need more investigation.

a) The path issue

C:\Users\brray\Documents\GitHub\skll\examples>run_experiment titanic/evaluate_tuned.cfg
Traceback (most recent call last):

    "config file does not exist"), train_path)
IOError: [Errno 2] The training path specified in the config file does not exist: u'train'

If I 'cd' into the titanic directory, it works.

You raise a good point. The relative paths in a config file are specified as if they're relative to the config file, but in actuality the paths are relative to your current working directory. We should probably fix that so that they're actually relative to the config file's location.
