fixed Addon.lua to use the unhooked EnableAddOn (still needs to be changed to grab from the interface) improved the error message when creating an Addon object on a Blizzard addon (will add direct support later) implemented the hooks on EnableAddOn and LoadAddOn rearranged functions inside Tree.lua, with some edits copied OptDeps from main module to the bootstrap module, to delegate loading to the client when possible
