OP-1577 Svg fixes for output calibration wizard
OP-1556 Changed ESC calibration procedure slightly.

Added even more warning artwork to ESC calibration to make it even more
explicit. Darwin awards might have lost even a few more poor souls by
this i hope.
Merge remote-tracking branch 'origin/thread/OP-1556_ESC_Range' into rel-14.10
OP-1574 Removed limitation to only allow Rapid ESC to perform calibration.
OP-1582 Set text to Next/Skip for Flightmode and Aux channels
Test CConfig file
OP-1522 Robustness of OPLink radio

Increase number of channels to 32 for all bit rates.
Synchronize clock on all channels.
Go into failsafe after 4 or 8 (one_way_link) missed packets.
Don't stay on channel 0 if we dropped a packet.
OP-1522 Include chan idx in frames

Include the channel index used in frames sent from the coordinator.
This is needed since it is possible for the modem to receive frames
sent on channel X while listening on channel Y if X and Y are close
together.
OP-1576: Remove unused tx_resent counter

Remove unused tx_resent counter and replace it with
rx_failure in link quality calculations.
OP-1522: Chane timeout logic

Use real time rather than missed pickets when deciding if we are
disconneted. Makes the link less sensitive at higher rates since
higher rates means more chances to get a packet through within the
given time.
