Working on cookies. This includes having a function generate_random_fixnum to assign session_id's in the @sessions hash. generate_random_fixnum returns numbers near the maximum of fixnum itself, to help minimize the chance of collisions. The seed for the random number generator is based on the time, and set at the instantiation of the TastyNoodles object. So with each reboot, the seed is renewed. Right now tastynoodles can receive cookies and send cookies, but internal storage of cookies in memory is still up in the air. Storage in an instance variable for session cookies perhaps?
Added a new way to split the request string into a request array. It used to be split on space, now it's split on crlf, then further split on space as need be.
Tastynoodles now does session cookies.  Tastynoodles grabs the cookies before processing the request, and then hands the cookies back when building the response. Also did some code cleanup, removed hardcoded_response instance variable.
