Flag 2.x changes+ flag_abuse issue

This is more a FYI than anything;

To my understanding, flag module has a 2.x branch that has various features; including a way to alter options (it's a drupal_alter instead of the hooks that someone else proposed). May be a good idea to wait to change flag_note into flag_history and flag_note till flag 2.x-dev is more ready and make a 2.x instead?

Anyhow one of those changes with the alter is additional events are possible. flag_abuse module is using that to change the $action for a global reset option it needs (ie insted of just flag, unflag it's flag, unflag, reset as actions with flag_abuse.)

Flag note changes the link to flag/note/etc. and uses the flag_note_page, which only handles flag/unflag. If neither are supplied there's no error handling (case statement doesn't have a default). and the page returns as a white page. For now, might be a good idea to call flag_page in default case statement. (here's the issue in #601724: Issue with flag abuse+flag note filled in flag_abuse; wasn't sure which module it should have been filled under).
