Allow default admin menu in Groups component to be editiable.

[DennisSmolek]

Currently when you use the default groups component there is no way to remove any of the subnav items under the admin tab.

For example:
My client wants to remove the "Delete" function from the admin menu for non site admins. They can change other admin parts but she doesnt want them to be able to do this. Currently there is no way to resolve this easily without removing the core function totally. (bp_group_admin_tabs)

I suggest either passing an exclude option when calling the function or running a filter with an array of included tabs.

Yes, its not hard to copy/paste the code without the tabs but its a ton of extra unnecessary code.

Good idea. It would be nice if we used our own API for this - bp_core_new_subnav_item(). DennisSmolek, want to take a swing at a patch?

The navigation API, introduced in r10745, v2.6, addresses this.
