Review request for kdelibs.


Summary
-------

This adds support for middle-clicking on the breadcrumb folder menus to open them in a new tab.  This adds what I feel is useful functionality and makes the menus behave consistently with the rest of the breadcrumb bar.  

Note that middle-clicking does not close the menu.  This would both be more difficult to implement and, I think, inferior in terms of functionality.  Doing it this way allows people to open multiple tabs without re-opening the menu (or, better yet, a sub-menu).  Further, simply clicking outside the menu closes it (which you would need to do to get anything done anyway).  So there is not much cost to doing it this way for people who only want to open one tab but there is a large benefit for people who want to open multiple tabs.

Testing
-------

Middle click opens a new tab both on the main menu and the new "more" sub-menus.  I'm not sure what else I can test, the patch is fairly straightforward.


Thanks,

Todd
