Just downloads the URI detected by saturnin_www to $HOME

saturnin v0.0.21+ adds new flexible menu handler so we don't need to
keep long pipes around in i3/config

Added feature to *uba* to launch browser even if list of URIs on stdin
ends up empty (that is, zero size or only empty lines).

uba will launch Uzbl for eacy URI on STDIN, so it's easier to link with
saturnin-www or any other command while keeping it simple and unix-y.

Original scenario of opening always just one URI can be easily achieved
using `head -1`.

Too often, minus got confused with 0.

... which I now officially started using instead of xfce4-notifyd

The action behind +Shift version is more common; make it easier to use.

Thos makes it easier to quickly abort the mode if entered by accident.

 *  Remove comments and unused bindings.
 *  Move mode binding to front>

We did not use `reload` anyway

Now all the 'ub' wrapper needs to do is launch browser with URL that
is obtained by passing all parameters to saturnin-www:

    #!/bin/bash
    exec uzbl-browser "$(saturnin www "$@")"

Forget about tabbed mode in urxvt

Starting with ffoo 0.0.14, new default is to pick only the first file
from FFOO_INI_PATH.  The old behavor can be triggered by using `-j`

Preserve comments and empty lines to allow for better orientation in
the merged list.
