core, quick_frontends: android compatibility hacks: a couple of hacks have been used so backend can be launched on android using kivy - config file (sat.conf) is been read on a specific dir, using a detection of Cagou domains in constants.py - fixed crash when using sys.stdout.isatty in log_config.py - Q&D fix for logging encoding issue on android - when android is detected, the path/pattern to load plugins is modified - SRV is not working at the moment on android. If the platform is detected, the host is used directly with default port. A hosts_dir configuration can be used in [android] section to map a specific ip to a host - getRepositoryData in tools/utils return constant string on android. Proper repository data need to be copied during package building. - [quick app] more robust failure handling on asyncConnect error - [quick chat] default to utf-8 when getlocale doesn't return the actual locale.
