B2-rc3
Beta 2 Release Candidate 4
Changes since RC3:
* The host application can now install and run as a service removing
the need for PsExec or a scheduled task to start the application.
* There is now a NSIS installer for the host application which
installs the service and will handle seamless upgrades without the
need to uninstall prior versions.
* The host application now runs with `High` scheduler priority
* The host application will now stop capture and go to sleep if there
are no subscribers (clients).
* The host application no longer opens the log file but instead shows
it's location. This is to prevent the elevated process from being
abused to run processes as the `SYSTEM` user account.
* The client framebuffer copy spinlock is less agressive preventing
CPU stalls on some systems due to starving the system scheduler.
* Installing the spice guest tools no longer breaks mouse support.
