Logofrag - Fixed the Session

As I predicted, work on Logofrag is going along very slowly (something to do with schoolwork being so time-consuming and Etho being so entertaining).  I did some reading of the MSDN ASP.NET docs and discovered that, unlike Request.QueryString, Session items are Nothing by default.  I had been doing all kinds of stuff to see if it existed, make sure it was an integer, and parse it appropriately.  That was useless because I could just shove an Int32 into it and then retrieve that exact same value later.  So, I went through the small codebase and removed the string-parsing logic from accesses to the logged-in user ID.  Progress!
