Scanner now pauses when a signal is found #88

Scanning - memory and frequency:

the scanners now pauses when a signal breaks the squelch threshold.
Overlay a bar on the vertical S-meter to show the squelch level
Updates display to show listen vs scanning
move the rotary left or right to continue
short press on "menu" -> launches scanner_radio_menu() with a subset of the main menu for quicker access
long press on menu -> select station and quit
any press back -> quit and restore radio settings

TODO: only resume scanning if no signal for > 'n' seconds

Behind the scenes:

Expose squelch state so the scanner can use it
factored out draw_vertical_dBm( 124, power_dBm);
created dBm_to_63px(float power_dBm);
