Added features to the BEACON ledstrip profile:
Added a `ledstrip_beacon_color` to allow color selection rather than forcing to white.
Added `ledstrip_beacon_period_ms` to configure the blink period in milliseconds. Smaller time periods mean faster blinking.
Added `ledstrip_beacon_percent` to configure the "ON" time duty cycle. User can set to 100% to have the beacon display a solid color. 0% can be used to turn the becaon completely off.
Added `ledstrip_beacon_armed_only` to allow the user to configure whether the beacon is only on when armed.
Added `ledstrip_visual_beeper_color` to allow configuration of the visual beeper color.
Added the new parameters to the CMS menu.
Simplified the code and combined the RACE and BEACON profile processing.
Added support for auutomatically displaying a beacon that indicates RX_SET or failsafe regardless of the other RACE or BEACON settings.
