Small UI fix

[simon-riou]

• [x] Move camera temperature under image source
• [x] set the color red over 80% and the color orange over 30%
• [ ] Add the gpu temperature at anytime on the last line of the information panel

after searching, it seems that to add the gpu temperature, you need to use another librairy and to compile with a flag so i don't know if michael still wants it
