Support of multiple menu's

Let me start with the message: I find this module simply brilliant, it helped me out so many times.
However during my projects, I also noticed that menutrails restricts some of the choices, which shouldn't be the case.

The following situation occurs:
You have a single content type called news.
You also have a views with an overview of these nodes.
You don't want the link of the overview page in the primary or secondary links.
You do want the trail of news content type to include the menu item of the overview page

To make this work, you can use a workaround:
1. Put an menu item in the primary-links to link to the overview page
2. Select the menu item in menu-trails
3. Make the menu item inactive

This will work as long as you don't change the settings in the back-end.
As soon as you change any settings, you will loose the breadcrumb and will have to repeat the process.

I found out that this restriction can be solved by allowing menutrails to be build up from several menu's
- This will open the option for people to use menu items from any menu they selected in the back-end.
- Allow people to create a dummy menu, to put menu items in they don't wanna show on front-end but do want in menu-trails.

I included a patch to help with this issue,
