make bb_new_user() pluggable

[so1o]

the new user creation process is currently very rigid and cannot be overridden without making changes to the core files.

any other ideas guys.. im running out of steam here..

I would probably just put bb_create_user() in bb-includes/pluggable.php so that it can be replaced by a plugin rather than using a filter to accomplish that. We only need it to be replaced by one function, we don't need the ability to hook many functions onto the filter.

Also, does bb_new_user() ever need to return both the user_id and the password? I'd rather it only returned the user_id even when BB_INSTALLING. We can rewrite the install script to take advantage of the bb_new_user hook to grab the password.

if we put it in pluggable.. nope we wouldnt need to return the username and pass

[so1o]

pluggable bb_new_user and change to return user_id always

[so1o]

(In [638]) pluggable bb_create_user() from so1o. Fixes #495.
