RiotWatcher.get_summoner fix
RiotWatcher.get_summoner fix

Since get_summoner relies on get_summoners output, it failed when the literal name was used to index into the returned dictionary. The dictionary returned by get_summoners lowered the input name and removed spaces. I just added a string replace to remove spaces and lowered the text. 

No clue how more exotic characters interact with the api but this should fix some of the more minor ones.
