Re-structure sources used by main and renderer processes

[veado]

A lot of changes here, but 99.9% is just moving content around to have sources in a new structure:

├──  src
      ├── main      # sources of main process
      ├── renderer  # sources of renderer process
      └── shared    # shared sources

Depends on #281

Closes #275

have a question about renaming electron -> main. if i understood correctly main is still an electron app. maybe leave a semantic name ?

small fixes at the comments.

Folders main and renderer are named after Electrons Main and Renderer Processes. We have already used these naming for packaging: electron-renderer and electron-main. You will also find ipcRenderer or ipcMain in Electron (Note: xyzRenderer, xyzMain). I think it's still fine to use these names for our folders, which are all in the sense of Electron.
