Adds support for two new actions:
* `globalSummon`, which can be used to activate a window using a _global_ (READ: OS-level) hotkey.
- accepts an optional `name` argument. When provided, this will attempt to summon with the given name. When omitted, we'll try to summon the most recent window.
* `quakeMode` which is `globalSummon` for the `_quake` window.
These actions are stored in the actions array, but are read by the `WindowsTerminal` level and bound to the OS in `IslandWindow`. The monarch registers for these keybindings with the OS. When one is pressed, the monarch will recieve a `WM_HOTKEY` message. It'll use that to look up the corresponding action args. It'll use those to try and summon the right window.
