Highlight logged-in user in net check-ins

[cjtheham]

The Netlogger interface highlights the logged-in callsign if checked into the net with I believe a neon blue color. It makes it easy to spot where you are in the "queue" if it's a roundtable net so you do a bit less searching - especially on mobile. I think Ragchew should probably have something similar, although maybe some other kind of indicator of "this is you" could be useful.
