[gcs] [ground_segment] [speech] added speech_name feature so the audible alerts on the GCS can use an alternate name other than the aircraft name, defined as another field in the conf.xml aircraft entries, no entry falls back to using aircraft name. Note that still not complete, need to fix handling in paparazzi center as right now it deletes the field out of the xml file
update .gitignore
[stm32][i2c] move debug_led stuff to extra file, the driver still needs proper cleaning
Setting pulse_type for stm32 architecture doesn't do anything. Fixed this now.
fixed ezuhf file
Merge pull request #343 from gtoonstra/ppm-negative-fix

[stm32] actually honor PPM_PULSE_TYPE_NEGATIVE and trigger on falling flank
Merge pull request #344 from gtoonstra/ezuhf-config-fix

[conf] fixed ezuhf file (valid if ppm pulse_type fix for stm32 merged).
[dox] updated doxygen comments for spi interface
[gcs] [ground_segment] [speech] speech_name feature now uses GCS section with SPEECH_NAME defined in the airframe xml file instead of the conf xml file. Reduces impact on ground segment (no paparazzi center mods required).
Merge pull request #340 from scdwyer/speech_ac_name

New feature: speech_name for audible alerts

Adding some doc to the wiki for this would be a good idea

Revert "[conf] remove duplicates after setting all flags and sources"
Doesn't work as intended (yet).
The sorting e.g. splits up `pkg-config glib-2.0 --cflags` into
--cflags` glib-2.0 `pkg-config
so it doesn't work anymore...
One way could be to make sure to resolve these first before sorting.

This reverts commit 70168207abc7f5c2b6a0fc766e03e8bf2b633009.
