Subject: Better browser OS detection.
X-Git-Tag: v1.0.0~409^2
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=230784066c7950316b8267a508406eb571e0ff79;p=mirror_novnc.git

Better browser OS detection.

Apparently Firefox on Linux changed the value of navigator.appVersion,
causing our OS detection (used to determine how to interpret different
modifier keys) to fail.

Use navigator.platform instead, which should be more stable.
