Add Android-specific options

Now the app can:
-Set the channel name and description
-Set the notification subtext
-Add a "Close" action to the notification, along with customizing the action text and icon

Fixed bugs:
-Icon is never used if it's in "drawable" rather than "mipmap"
-Used "Compat" library to make backwards compatibility easier
