new user email filters

[ansimation]

looked to see if there was a way for a plugin to actually edit the initial emails that are sent out when a user registers and there were no actions available so here's my patch. if you know of a way to do this without the patch then please feel free to let me know.

While those default messages are not currently filterable, they *are* defined in pluggable.php, in such a way that you can redefine the entire function if you want to do something totally different.

e.g. just defined your own version of wp_new_user_notification(), wp_password_change_notification() etc in a plugin, then activate it and it should override the core functions.
