snap support

[urbandroid]

snap allows applications to run on any snap installed linux distro securely via jailed settings. it is easy to setup your applications as a snap package and it is easy to use for clients. This way anyone who want to try your app won't have doubts about security and this will happen without having to go through whole codebase to be sure. Not only it is more secure also it is way easier for end user to just click install on snapstore instead of compiling, installing, creating autostart etc. also thanks to snap apps will automatically upgrade on background without an effort.
