function ctools_menu_local_tasks in Chaos Tool Suite (ctools) 6

CTools' variant of menu_local_tasks.

This function is a new version of menu_local_tasks that is meant to be more flexible and allow for modules to dynamically add items to the local tasks using a simple function.

One downside to using this is that the code to build the tabs could be run twice on a page if something
