bindsym/code: add group support

Browse source 
This adds support for specifying a binding for a specific group. Any
binding without a group listed will be available in all groups. The
priority for matching bindings is as follows: input device, group, and
locked state.

For full compatibility with i3, this also adds Mode_switch as an alias
for Group2. Since i3 only supports this for backwards compatibility
with older versions of i3, it is implemented here, but not documented.

Binds _key combo_ to execute the sway command _command_ when pressed. You
may use XKB key names here (*xev*(1) is a good tool for discovering these).

released. If _input-device_ is given, the binding will only be executed for
that input device and will be executed instead of any binding that is
