OpenVR support plus some fixes #45

So here is a rather large PR, it adds OpenVR integration to wowlet via an alternative QtQuick (QML) interface on windows that acts as a SteamVR overlay. The feature is in src/vr and is only compiled/included when passing the -DOPENVR=ON CMake definition, so for Linux/MacOS compilations there are no changes needed to the build system (famous last words).

This feature was made with the input from a VR community that likes to hang out in VRChat and go to "VR parties" (yes, with DJs and stuff). The idea is that such communities can now tip eachother whilst staying in-game =D

deps/build

For the Windows dockerfile, there have been some changes to CMake and Dockerfile.windows to facilitate QML apps:

Compile Qt with some more components like "QtQuick, QtMultimedia, QtQML, QuickControls2" and so on.
Introduce QML and OPENVR definitions.
Introduce libpng and libzlib dependencies

2 new external libs were added to the project itself (in contrib/)

quirc via submodule (QR code scanning)
Valve OpenVR (vendored because a bunch of patches were neccesary to get it to compile)

The app

The QML app can be found in src/vr/qr/. It is loosely based on OpenVR-AdvancedSettings and is made as a SteamVR overlay.

You may send people money in 2 ways:

By looking at a QR code in-game and scanning it. src/vr/QR-Code-scanner
By talking to your recipient via chat and giving them a 4 digit code (10min expiry). wowlet-backend:wsparse.py

In addition, the interface also has the ability to:

Open regular Wownero wallets you already have
Create Wownero wallets
Show your balance in fiat
Send Wownero by specifying the amount in fiat
Streamer mode (hide balance)
Support for themes (default and WOW theme included currently) - see src/vr/assets/themes.json
Copy receiving address to clipboard
Save QR code image to disk

So, it's a fully fledged wallet for virtual reality.

This allows people to tip eachother in-game and/or game developers to integrate Wownero payments in the core gameplay of their games.

This PR has been tested for 2 weeks now - The normal, QtWidgets interface works just fine. The QML interface (VR) can be considered Beta, but it's useable.

Additional changes

Tor has been updated
FeatherSeed has been fixed
The websocket server has been updated (this fixes fiat price lookups / suchwow images / adds more remote nodes)

To-do:

Check if Linux still builds
Check if Mac OS still builds
