Split up into modules and add float module
Split the app/ module into three modules terminal/ - Terminal emulator library module. view/ - Terminal view library module (depending on terminal/). app/ - The main Termux app (depending on view/). Also add the float/ - The Termux:Float app (depending on view/).
