Add support for Temperature System about openwebnet-android

I can have a look if you want.

All right, just few hint

• we should handle conversion between celsius/fahrenheit? using a spinner in the activity?
• I would like to change the font, like digits only for the temperature value: see FontViewHelper, we should also remove unused fonts!
• we should be able to increase/decrease temperature

Before start we need to discuss how to handle FloatingActionMenu.
I think we could add Temperature, Sounds, Ipcam and other less frequently used actions to menu/menu_main.xml and handle correctly DEVICE_DEBUG icon.
What do you think?

I think that we sould create a new issue for "determine what goes in the FloatingActionMenu".

Regarding the Temperature feature, this file gives plenty of information but is not very reader-friendly.

The temperature features in MyHome seem much more complex than Lighting or Automation. I think we should proceed iteratively and maybe start with something relatively simple: only show the current temperature. Once we have that we'll move forward with more interesting things. What do you think ?

For fab see this issue.

About temperature, agree with you about starting only from reading value.
Moreover I would like to document also each supported message/frame from rx-openwebnet, I already opened an issue
