bl-x-www-browser-pipemenu: select default browser should exit with a message...

[capn-damo]

...if only one browser is installed.

When running the command in a terminal:

sudo update-alternatives --config x-www-browser
[sudo] password for user: 
There is only one alternative in link group x-www-browser (providing /usr/bin/x-www-browser): /usr/bin/firefox-esr
Nothing to configure.

If run from the menu item, the screen just exits without informing the user there is nothing to configure. So causing confusion to a new user, who may think there is a bug! https://forums.bunsenlabs.org/viewtopic.php?id=2867

The easiest fix is to put in a delay before closing the terminal:

menuItem 'Select Default Browser' "x-terminal-emulator -T 'Select Default Browser' -e sh -c 'sudo update-alternatives --config x-www-browser; sleep 6'"

But an alternative would be to make $INSTALLED an integer, increment it each time an installed browser is found, and check if it's greater than one before displaying the menu item.

That second alternative mentioned above would miss browsers installed by some other route. For now, let's just add the 6 sec sleep.

Now done in deuterium branch. (sleep dropped to 5 sec)
