key-binding: sort binding lists

Browse source 
Sort bindings such that bindings with the same symbol are sorted with
the binding having the most modifiers comes first.

This fixes an issue where the “wrong” key binding are triggered when
used with “consumed” modifiers.

For example: if Control+BackSpace is bound before
Control+Shift+BackSpace, then the latter binding is never triggered.

Why? Because Shift is a consumed modifier. This means
Control+BackSpace is “the same” as Control+Shift+BackSpace.

By sorting bindings with more modifiers first, we work around the
problem. But note that it is *just* a workaround, and I’m not
confident there aren’t cases where it doesn’t work.

Closes #1280
