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. Patch by: Pawel Solyga Review by: to-be-reviewed

    The Geographic Mixin class provides routines for geographic objects,
    however, it is no longer necessary, since all of its previous functions 
    may now be accessed via the GeometryProxy.  This mixin is only provided
    for backwards-compatibility purposes, and will be eventually removed
    (unless the need arises again).
