Make it possible to receive files 

The files are saved to $HOME/downloads/, after which the user
may choose to open the downloads/ folder or edit the file with
the $HOME/bin/termux-file-editor program.

It's also possible to receive URL:s, in which case the
$HOME/bin/termux-url-opener program will be called.
