Javascript functionality that enables the following:
- it will capture any parameters send to the page as a GET request with specified name
- it will set a session cookie with the value of the specified name, session cookie to be available on the whole of the top level domain
- reservations links are now called by javascript. They will go through weblet relocate and will have a specified parameter appended with the value of the cookie
- the reservations link function will also be called from Flash movies.
