v1.2.1: noVNC OK, Tidy-up GUI

🚀 Feature

• Module Config tab, allowing for configuration of the VNC Secret
• Reboot command/action added to Client Area (ie. on/off/hard-off)
• Link from Health tab of Admin GUI to WHMCS Marketplace re: reviews
• Images for all supported Operating Systems & Kernel types (some fixed)
• Ground-work for noVNC overhaul, to support PVE Auth & VNC Tunnel tickets

💅 Polish

• Stop VM/CT (Client Area) renamed to Hard Stop, compared to Shut Down
• Modify the PHP API2 class, adding getTicket() so we can dual-auth (VNC)
• Move VNC Clients from root-level to vnc-only-level access to Proxmox VE

🐛 Bug Fix

• noVNC render method updated to stop out-of-order data flow problem
• noVNC back-end vncproxy and vncwebsocket methods updated re: spec
• Client Area actions (Power Off/On, etc) fixed for LXC (QEMU OK)
• Error with both VNC methods. We are going to remove TigerVNC
