[generators] gen_airframe: don't force float if unit = code_unit
[fixedwing] if USE_BARO_BOARD: separate baro timer

before baro_periodic was running at PERIODIC_FREQUENCY in sensors_task,
which is too fast for ms5611 if periodic freq is > 100Hz
[lpc21] don't override T0CCR values when setting ppm and trig_ext
possibility to pass ref to paparazzi_version
[baro_board] make configure work for BARO_PERIODIC_FREQUENCY (needed to use define before)
[sys_time] maximum of 16 sys_time timers by default (was 8)

actually makes the baro periodic timer (for BARO_BOARD) usable by default on fixedwings
[ins] alt_float: if USE_BARO_BOARD, dt is 1/BARO_PERIODIC_FREQUENCY
[baro_board] ms5611, error if BARO_PERIODIC_FREQ is over 100
[rotorcraft] only go to HOME mode if in NAV

then you don't have this "failsafe" in manual modes anymore,
but it will prevent issues like #850
[airframes] fix quad_navgo actuators for nps
add HBMini - Board files
Add confs for HBMini
[simulator] fix flightgear viz on 32bit systems

all current fg versions have that padding1 var, hence also no need for pack pragmas
[build] remove 'load' target from makefile

It is a special command in Make 4.0
update create_module helper
code style formaters

fix_code_style.sh script uses astyle which works very well.
Eclipse is not very good at this, but better than nothing...
[flight_plan] set primitive should not delay next stage

when a set is called, it should not stop the navigation for 1/4 second.
[flight_plan] fix return primitive
[release] v5.2.1 stable version
