Ambient vs. ambiant spelling

[shipmints]

I just discovered Hot (and Sensors) and thank you to you and all that have contributed. One thing I noticed is the English word "ambient" is misspelled "ambiant" on display labels. I'm guessing one or more authors are French speakers so that would make some sense, yet when the UI is displayed in English, it should be "ambient".

The source code also misspells ambient but it wasn't clear if that was in French or English but it seems mostly English so perhaps refactor those names, as well for consistency in searching the code base.
