WebDAV info dialog on remote desktop no longer displayed automatically.
Removed out-of-date comments in WebDAV functions, saying "Only for
MASSIVE".

Added a comment that the "displayWebDavAccessInfoInRemoteDialog"
method might not actually display a remote dialog, depending on
the siteConfig.displayWebDavAccessInfoInRemoteDialogCmd.

NOOPCallback in showKillServerDialog has been renamed to
ShutdownKeyDistCallback, because that's what it does now.
The "SHUTDOWN_KEYDIST" event was added because of the
Launcher's new "public_mode" feature, which requires
cleaning up the key.

In the killServer method, the next event is now "SHUTDOWN_KEYDIST",
instead of "SHUTDOWN", again to ensure that keys are cleaned up
properly on shared "Guest" accounts.
Now using ephemeral port for WebDAV on remote desktop, instead of 8080.
Thanks to Chris for this fix.
