[PATCH manager 1/2] fix #5475: configurable window title

[Thomas Ellmenreich <t.ellmenreich@proxmox.com>]

Allows for setting of the new 'window-title' datacenter.cfg option
through the ui.

Adjusted the index.html templating to construct the correct window title
on every request according to the cluster configuration.
