update CHANGELOG
lat/lon int in 1e7 deg instead of rad

so we don't loose resolution by converting and storing as radians
[messages] rename class to msg_class

makes it possible to use the python parser using xmlobject since class is a reserved word.
[ins] fix typo
[modules] fix nav_spiral

no generic variable/enum names in headers...
Also add it to nav_modules flight plan and test it with microjet_lisa_m
[tests] use conf.xml and exit with number of failed tests
add initial travis ci config file

first build paparazzi itself, then compile all test targets
[tests] cleanup 01_compile_all_test_targets.t

Check exit status instead of whether output contains the word Error.
With ForceArray on xmlSimple no need to check for target separately.
Also don't filter on list of firmwares, build all..
[test_progs] fix compilation of test_actuators_pwm if also using setup_actuators.xml settings file
[Spektrum] Configure the bind pin to be pullup/pulldown.

All Lisa/M and Lisa/MX prior to V2.1 don't have a dedicated pull
resistor on the bind pin. We were configuring the pin as floating input.
This will result in random behaviour, depending on the charge of the
GPIO. The system will decide to set the satellites into bind mode
depending on how much moist finger is present on the pin. We want
something more decisive than that. :)
Merge pull request #814 from esden/spektrum_bind_pin_fix

[Spektrum] Configure the bind pin to be pullup/pulldown.
[module] module to control a HackHD digital camera
[ins][invariant] fix mag orientation and add support for rotorcrafts
[boards] Added Lisa/M and Lisa/MX V2.1.

The only major change to v2.0 related to software is the fact that
we have a dedicated Bind button now and are not misusing the ADC1 pin
any more. Otherwise the changes are mostly mechanical including the
integration of Aspirin V2.2 into the board design.

closes #813
[conf] update wiki urls
update CHANGELOG
[release] v5.2 stable version
embarking upon long road to next stable release
[rotorcraft] horizontal guidance reference refactor

make the reference model adjustable at runtime via settings
