Token + Flag + XMLSitemap Menu = undefined index "token type"

This is one of those cases where the problem isn't really in this module, but I feel like it is Token's responsibility. When Flag, Token, and XMLSitemap Menu are all enabled, there is an undefined index of 'token type' on line 88 of flag.tokens.inc, in flag_tokens_info(). token_entity_info_alter() is supposed to put that key in the entity info, so I started trying to figure out which entity type was broken. It turns out that it's "menu_link", which is a type added by xmlsitemap_menu_entity_info_alter(). Naturally, token_entity_info_alter() runs before xmlsitemap_menu, and it's definition of menu_link doesn't include a 'token type' key.

Now, any of these modules could be patched to fix this problem, but I feel that if Token is going to try to add this key to some entity types, it ought to try to do them all. And the obvious solution to that is to make its implementation of hook_entity_info_alter() be last in line.
