Provide developer option to override/disable global hotkeys on desktop

[amcclain]

Hoist installs several global hotkeys via desktop AppContainer - this could be problematic if an app wishes to use one of the combos for its own purposes - e.g. a custom data refresh handler.

hoist-react/desktop/appcontainer/AppContainer.ts

Line 191 in 7cbfba9

function globalHotKeys(model) {

Would like to have more control over this, without having to write a custom AppContainer component.
