Bugreport TODOs

[CRImier]

We now have bugreporting that can be used for ZPUI and ZeroPhone debugging. However, there are things we could wish from it, of course.

• Add usage examples in "Howto" for app developers
• Add proper date&time timestamp generation for the filename
• Add bugreporting (with prompt) to the Avrdude app (when flashing fails)
• Allow reading the default FTP location from a config file available somewhere globally (currently, hardcoded in /libs/bugreport/bugreport.py.
  • This would allow for custom servers
• Add opt-in automatic log sending on exceptions
• Allow sending the logs that were stored when network connection wasn't available (can workaround with "Custom file" option, for now)
• BugReport: add send_from_stored method
• BugReport: rename save_in to store_in
• BugReport: add send_or_store method that would allow apps to avoid duplicating the try: send; except: save code
• Add a function to notify about privacy policy changes (showing a diff to the user)
