the 'drop z' method reduced the impact of noise on omegaI, but it also
made us more sensitive to errors in accelerometer calibration and
scaling, as demonstated by the logs from Gabor here:

Simulation testing shows that the other noise suppression methods
applied in the DCM code, in particular the slope limiting on omegaI
the removal of the weighting and the upcoming use of a _omega_I_sum
buffer have reduced the impact of noise enough that we can now safely
include z in the acceleration calculation.

fix udp and tcp connections

DataFlash_APM2 - moved CS_inactive call (which disables the dataflash) from the beginning to the end of all methods.  This means the dataflash does not monopolize the SPI bus.
    Also formatting changes to use tab instead of space. Sorry, should have done this as a separate check-in to the above changes.

fix turn radius length (100m)
modify 3dr radio options
modify heli Setup

This is a test

add arduplane level
more image georef options - now does gpx for dronemapper.

language by hazy
move turning circle to be based on cog
add APPROACH
add autodec on/off
mod 3dr radio uploader to read in 64 byte packets
add more georef caching. much faster now on more than 1 run.

add some Chinese translation

This is better since each project has very different options.

add ability to geotag images from log file. - will release guide soon
