Fix for email change not working in profile/settings

[gian-ava]

If you go in profile > settings and try to change the email, it doesn't work.

You need to change "bp-core-settings.php" line 41:

WPINC . '/registration.php'

to:
ABSPATH . WPINC . '/registration.php'

That fix it.

As suggested from Brajesh Singh in this thread:

1.2.3 works fine for me without making the change, needs further investigation.

Works for me too on 1.3 bleeding, though I'm not sure why. Seems like it shouldn't.

Same result as Boone on 1.3-bleeding and on a standard WP install of 3.0.3.

However, we should probably patch the line so it uses "ABSPATH . WPINC" for sanity's sake.

Quickly tested the change on the same setup and it works fine.

(In [3578]) Corrects path to registration.php in bp_core_screen_general_settings(). Fixes #2285; props gian-ava. Also fixes some WP_DEBUG problems in the blogs component.
