VIrtualHere USB Server 1.8.4 Released

* Synology - now installs a help icon in the Main Menu of the DSM
* Synology/QNAP/ReadyNAS/Ubuntu Server/Android - will only take control of the usb bus when a device needs to be shared rather than all the time. This means the usb device will always be usable on the NAS/Server if it is not being used remotely.

QNAP - Fixed "Resource unavailable" error message
