Remeber cookies of collapsible for all contexts

I don't know why cookies of collapsibe are restricted to contexts view,edit and comment only. it would by nice to make cookies for all contexts beacuse then you could use collapsible for leftmenu with consitent behavior in all views (also for login, attachment, etc)

today -> var cookie = Wiki.Context.test(/view|edit|comment/) ? "JSPWikiCollapse"+ name: "";
better -> var cookie = Wiki.Context.test(/.*/) ? "JSPWikiCollapse"+ name: "";
