bp_is_activity_front_page() broken when BP used on secondary blog

[r-a-y]

If BP_ROOT_BLOG is set to anything other than 1, bp_is_activity_front_page() breaks.

The reason is bp_is_activity_front_page() utilizes bp_core_get_site_path(), which will always return "/" instead of checking the $current_blog->path.

The attached patch fixes this.

[r-a-y]

Actually, for subdomain network installs, bp_is_activity_front_page() should still work.

I meant to say for subdirectory installs, bp_is_activity_front_page() will break.

Can someone test this patch against a multi-site installation and a BP_ENABLE_MULTIBLOG situation also?

I can see there's an issue here, but I have a feeling that using bp_core_is_multisite() isn't always going to return the desired result.

[r-a-y]

Tested on a subdirectory multisite install with BP_ENABLE_MULTIBLOG set to true.

Works. Haven't looked too much into bp_core_is_multisite() though.
