REMARKS:
This function is called by the wxApplet's when they need register a cookie
of data in the applet window's cookie table. Cookies are arbitrary data
objects that are references by unique name's by the wxApplet. These
values can be used to store and retrieve data that needs to remain
persisent across invocations of the wxApplet. Ie: The first time an
applet is created it would use the cookie to store data to maintain
it's present state so that if you navigated back to the same page
is would be able to re-load the prior state as though the applet
was never actually destructed.
Note: If a cookie with the same name already exists, this function returns
false. Hence if you wish to replace a cookie you should first call
UnRegisterCookie to ensure the cookie is deleted and then call this
function.

cookie of data in the applet window's cookie table. The data in the
cookie itself is also deleted before it is removed from the table.
