E0337: A hook found by its name

A live page's hooks are declared where they are written, with an attribute on the method: @ui.Mount, @ui.OnChange, @ui.Loads("group"). A method is never a hook because of its name. A method named Mount or Changed — the names earlier releases found the mount and change hooks by — that no attribute marks is refused, so a 1.x hook can't quietly become an exported method the browser calls. Mark it, or rename it if it is meant to be an event. A deferred group's loader named Load<Group> is the same mistake, reported as E0324.

vuka fix hooks adds the attributes. Reported by the compiler, by vukavet, and at start-up.
