My proposition of 0.5 release

Hi Dale!

Please take a look on this changes that I would like to propose.
1. < cooke:get /> tag is marked as deprecated becouse we can use < g: cookie/> instead
2. Service methods get() set() and delete() are renamed to same names as the exposed to response: getCookie(), setCookie(), deleteCookie().
3. New methods findCookie(), setCookie() and deleteCookie() that takes Cookie class as param (used in my work project).

I try to keep backward capability.
Also there is an error https://github.com/dalew75/grails-cookie/issues/3
