Add pylint configuration file (pylintrc) and do_pylint.sh script which runs pylint checkers on Melange code using pylintrc file as config. do_pylint.sh as default shows additional information like reports, TODOs, code similarities and unused imports, but you can run it in silent mode (--silent) which disables all of that. The only problem with unused imports in pylint right now is that it doesn't work in the situation described in last example at http://code.google.com/p/soc/wiki/PythonStyleGuide#Packages, so sometimes we get unused import soc when we actually shouldn't. However this can be fixed by writing pylint plugins (our own checkers) in future.
