[PATCH] ui: add URL for static configurations to load a specified file

[Sam Mendoza-Jonas]

Hey Nish,

This all looks good!
When testing this I ran into a problem that may just be down to my
machine, in that when device_handler_process_url() gets called to check
the URL, the network apparently hasn't *quite* finished configuring, and
wget returns "Unable to route to host". Have you seen this in your
testing?

Cheers,
Sam
