add msp telemtry
HoTT code cleanup.
Adding unit test for some gps conversion code to demystify it.
Updating Development docs.
Updating documentation.
Updated GPS logitude/latitude calculation.

The existing implementation that was ported over was trying to work with
different values.  By writing a unit test for the code that stores
values in GPS_coord it was possible to have known values which could
then also be used to write a unit test for the HoTT telemetry which
finally enabled production code to be written.

Hopefully it will work, unable to test further since my GPS unit is
playing up.

Refactor telemetry MSP.

BOXNAMES is repeated in case the first transmission is never received.

Each time sendMspTelemetry is called it executes one and only one
command.  There was nothing wrong with the old approach which sometimes
sent more than one command each time sendMspTelemetry was called but
this is simpler and there is far less duplication.
Updating developer docs.
Latest binaries - Using latest GNU ARM Tools, (2014-q1). F30x targets
now with FPU enabled, HoTT GPS telemetry cleanups, MSP Telemetry.
Updating telemetry documentation.
new Baseflight PID

full gyro scale is used now
and a new pid with float calculations was added based on PIDrewrite
eeprom size was also increased from 1kB to 2kB

Merge pull request #15 from nico-dh/master

adding doc for building in windows
Updating the L3GD20 scale factor and resolution based on Lux's comments
and feedback.  

Apparently 500 is 'not enough unless you're just hovering'.  2000 is
needed.

Previously the scale factor was guessed, incorrectly.
Merge branch 'master' of github.com:hydra/cleanflight
Updating I term for newpid to be 0.6f for a more locked-in feeling, as
per Lux's feedback.
Update HoTT GPS coordinate calculations.

It was broken for South/West values.

Added additional tests for maximum long/lat values.

Requires field testing to make sure values are correct on the telemetry
display.
