Desktop+ v.2.8.3

This is a hotfix update for the stable branch of Desktop+, mainly addressing SteamVR 2 keyboard compatibility. [b]Added:[/b] [list] [*]Added adjusted keyboard extension style for SteamVR 2 keyboard [*]Added workarounds for SteamVR hiding the keyboard when clicking anywhere outside of the keyboard overlay The keyboard behavior change was unexpected and messed up the keyboard extension. Desktop+ will force show the keyboard again if this happens while the extension is in use, but it's hacky and there'll be some flickering from this. [/list] [b]Fixed:[/b] [list] [*]Fixed keyboard extension not working with SteamVR 2 keyboard [*]Fixed floating keyboard size setting not working with SteamVR 2 keyboard [/list] Here we go again. Somebody forgot to look at the keyboard before releasing the last update.
