improve admin Devices > Devices page

[justinrh 290]

The admin Devices > Devices page is, uh, challenging.

1) no way to search or filter the hundreds of devices

2) most of the 700 devices are the SAME DEVICE and so should not be duplicated

Do you really have HUNDREDS (700?!?) devices? The Emby license is for one household.

There might be a way to better sniff the devices.
