dashes in username causes problems with search

fixed problem where users with dashes to start their names would interfere with proper search causing inflated numbers

example: /u/-Magitek-Armor- had this problem.

I added single quotes around the user's name when performing the reddit search and it gives the proper number now.  I did not test the bot but did test the web app version.  Example here: http://192.227.233.138/cReddit-Bot/credditrating.php?username=-Magitek-Armor-

Sorry about all the extra insertions and deletes, I believe that was Sublime Text 2 changing tabs to soft tabs.

TODO: when you click the link, the search is still sometimes empty though it gives the correct count...
