get_user_profile_link does not deal with spaces in user-login slugs

[_ck_]

$user->column needs to be urlencoded for spaces and other special characters that might be in username slugs from WP integration, etc.

ie.
replace:
$r = bb_get_option('uri') . "profile/" . $user->$column . etc

with:
$r = bb_get_option('uri') . "profile/" . urlencode($user->$column) . etc

This should work as far as mod_rewrite is concerned. We would want to change the logic a bit so that urlencode was only applied when "slugs" is the permalink type.

This is a knock on from the same issues as #687, let's track this problem in that ticket.
