Add Support for Enumerating Multiple SBC Vendors

[richbl]

DOES:
Currently, a DMS3Client is assumed to run on a Raspberry Pi, so the icon that's represented is the RPI logo.

SHOULD:
Should be able to configure the DMS3Client to include vendor type (e.g., Banana Pi, Orange Pi, etc.)

A good deal of work needed here, as all icons are currently font icons, and need to be pulled out into separate resources. As well, it appears that there are few good quality SBC icons out there...
