better "squelch" and coloring big numbers

When scanner finds a freq with high dbi, it locks into it "listening" a bit more (less than a second) for either confirm or discard it as an actual high dbi or just a spurious thing.

The big number frequency changes color accordingly: Grey = just scanning, yellow = locking in, Green = Found something, allowing the user to listen.
