Preliminary implementation of the Recommendations algorithm.

Proper test still due, due to the lack of dummy data to be used and the missing login process.
Added control code for currently logged in user.

Presentation tier code should call HttpContext.Current.User for the user parameter.
Changes made regarding DataSet select statements.

Mildly tested, no obvious bugs or exceptions thrown.
Right now, the program tests for logged in user through a string... if (user != "") ... might need to change that if required.
Added some documentation.
Got rid of an unused reference.
Added basic Game CRUD class.
