Nice online radio after a long long time...

Seems to whistle each time we save file, which is annoying if save takes
longer than moving to other focus (which may be very often).

(I should probably implement the memory part in bmo somewhere.)

Let's keep ini file names consistent with tool names.  Since bmo-uris is
gone, this is not even a shared file anyway.

Can be useul for emphasized/strong text in Markdown.

Externally stored because:

 *  vimb config could be a bit security-sensitive thing, at least until
    I find out what I want in there and how to split things properly.

 *  Same appliest to weechat, plus it has this habit of rewriting config
    on exit, which could become annoying if stored in git and changed
    frequently.

 *  Avoid icons that don't work well on Debian (conflict in Private Use
    Unicode area).

 *  Simplify battery statuses even more (with better understanding
    of ACPI statuses).
