Translated crow to "Butterfly", changed filenames accordingly to the english ones so its possible to change from english to german without the need of editing the Special Functions section per model.
Removed "Minimale Trimmung", in my opinion this makes no sense a trim only can be at maximum or at center.
* Change audio generation files accordingly
New way of working :
units files are ALWAYS named in english based on the names in audio_arm.cpp names.
multiple form (singular, plural(s) are ammended with 0 to 4 suffix, according to languages rules. example : meter1.wav for first form of plural of meter unit,. This filename needs to be the same for all languages (in their respective directories of course)
* Care for gruin9x
* Better form
* Other languages
* Cosmetics
Break up tts.py so that each language configuration of system and custom
sounds is done in a separate file, also fixing PEP8 problems with
tts.py, mostly whitespace related
