Hotkeys!

So, I've hacked together a small collection of key assignments for UI functions that I find essential for playing Civ6 without going blind, mad or otherwise becoming really irritated . Far from LUA competent, I'd like to open the subject for discussion and try to establish some sort of "best practice" approach to further key input modding. These key functions are working for me without issue, but could bear some scrutiny. My main concern is efficiency and not honking up UI performance. The first two add a means to toggle normally static UI map elements in order to produce a "clean map" view. Personally, I find this essential when hunting for resource instances or getting a general overview of territory. The others already exist as controls in MinimapPanel, but currently lack a key assignment. Perhaps Firaxis will add these... it seems strange that they're absent. toggle unit icons U toggle city banners X toggle resource icons R toggle yield icons Y I think 'heal' and possibly some other unit commands are missing assignments as well. I'll look to those after the map keys. All additions are made to DefaultMessageHandler in Ingame.lua. From experience with civ5, placing these here is the only(?) way to have the keys active during the entire turn cycle. Unit icons and city banners work exactly as in civ5... I only switched to uiKey from wParam, following current convention. For resources and yields, I lifted the functions directly from MinimapPanel. Perhaps there's a better way,
