Rich Presence support using Discord Social SDKHEADmain

Download DiscordSocialSdk-1.4.9649.zip
https://discord.com/developers/applications/1393451183741599796/social-sdk/downloads
to your ~/Downloads folder.
Add -DUSE_DISCORD:BOOL=ON to your cmake line.
The authorisation is triggered by selecting Help > Discord Social.
It seems that the user will need to do this every time they want Rich
Presence support on the viewer while using Discord.
The Discord app is still set to be a public client in the OAuth2 tab,
I'm going to try to make it work with the app set to be a confidential
client, next.
All Discord-related code are contained within one file, llstartup.cpp,
and other classes access it through some opaque layer, static functions,
otherwise we'd get these "duplicate symbol" linking errors.
