Ian Douglas Scott 67cb508802 keyboard: Refactoring of CcKeyboardItem handling of multiple combos
This commit includes all the changes that seem to be necessary for
CcKeyboardItem to be used for dealing with multiple keybindings, without
(yet) changing the user interface to expose this.

The `primary_combo` and `binding` fields of `CcKeyboardItem` are
removed, in favor of the existing `key_combos`. No combination is
"primary", since all of them can now be seen and changed equally.

We treat `CcKeyboardItem.key_combos` as a set, that a combo can be added
to or removed from. Though it continues to be represented as a `GList`,
instead of a `GHashTable`, to preserve ordering.

A lot of the keyboard panel code relied on the assumption that only one
combo can be set for each setting, so this required a variety of
miscellaneous changes.
