logical login redirect replacement for bp-default

[mikepratt]

In bp-default, the login form in sidebar.php redirects to

<input type="hidden" name="redirect_to" value="<?php bp_root_domain() ?>" />

which has the unwanted effect for the user of taking them away form their entry point to the site, forcing either a page back or suer that gives up on that page and moves on.

Suggest using:

<input type="hidden" name="redirect_to" value="<?php echo wp_get_referer() ?>" />

in order to keep the user on the page he was on when attempting to login, keeping the experience consistent

This would redirect them to the page they viewed before the page they logged in though.
