[ardrone] updated filter: use more data in case of spikes: only 1 package lost instead of 3
[conf] add simple x-mode quad jsbsim models
[conf] fix moments on x-quad jsbsim models
[conf] update krooz_sd fixedwing example

untested...
[boards] stm32f4_discovery: fix typo in ADC_3

thanks Chris
[ardrone] solved both type1 and type2 spikes: delayed temp versus delayed press
[stm32] fix typo
[boards] Initial support for Lisa/MX

the Cortex-M4 version of Lisa/M
[conf] add lisa_mx quad example
[datalink] add missing macros for UART4 and 6
[uart] replace #ifdef USE_UARTx with #if USE_UARTx
[tools] calibrate.py: exit with meaningfull error if optimization fails
[conf] use quad_lisa_mx as quad x-configuration example
use correct word in FP button to circle around a point
[fixedwing] settable LOW_BATTERY_KILL_DELAY

should probably be replaced by electrical.bat_critical instead of re-implementing the delay for the critical check there...
closes #610
[uart] if USE_UARTx instead of defined USE_UARTx
[tools] fix typo in get_id of calibration_utils
[nav] GetPosX and GetPosY in nav.h (FW) are in local coordinates

allows to use the macro with sectors detection

fix #602
[catapult] don't use GetPos macros but state interface directly
[rotorcraft] send motor_mixing.nb_failure in ROTORCRAFT_STATUS
