Check whether a menu is empty elegantly #142

Is your feature request related to a problem? Please describe. I currently have to rely on get() returning None to check whether a menu is empty, which is inelegant. I can't check the index of the currently selected item either because of #139.

Describe the solution you'd like An implementation of empty() on menu classes.

This is now fixed on the v0.1.5 branch with a new is_empty function for menus.
