Add ANT to the list of toggleable airplane mode radios

Adding ANT to the list of toggleable radios allows ANT to behave in the same way as Wifi or
Bluetooth in regards to operation during airplane mode: when airplane mode is turned on, ANT is
disabled, but can be re-enabled by the user at any time.

core: use 'normal' value for notification led off

Users can set this value to 250, 500, 1000, 2500 or 5000ms only,
but it's 2000ms by default.

With this patch, 'Normal' string is shown instead of 'By default'
and pulse speed goes to 1 sec.
