Added urllib-downloader koubae

[Koubae]

Added

download_images function

* extra_keywords default to None, so that pic can be search if only a keyword
* Change the default dir.
* Choose total pic to choosen value, if 'all' (capital doesn't matter) is passed, then download all found ulrs
* Parameter download, if False, then won't download, if True it will
* General refactoring

download_manager function

Same parameters as download_images but added

* multiprocess if set to True then it run in multiprocess mode
* debug => if set to True if will run log_to_stderr(logging.DEBUG)

logger

* Prints and add to log the messages from the functions

Fixed

* Readability 
* More user control

Removed

* os.getpid() for getting the os id I switch to current_process().name instead
we can also add Process().pid

* The download_page to downloader is delegaed to download both whole page or single url. 

Let me know what you think, I'm planning to add more functionallyty with argparse.
