### Description
This patch adds a dmenu interface to [setrule][setrule], which allows to add or
change client rules at runtime. It must be applied on top of [setrule][setrule]
and [menu][menu] patches.
You can invoke the menu by pressing `Alt+R`. The menu lists all the rules, plus
a shortcut to define a new one that would apply to the currently focused client
(marked with `(NEW)`). Rules that already apply to the focused client are marked
with `<`.
To edit a rule, you need to select it, press `Tab`, change what you need and
finally press `Enter`. You can remove a rule by prepending it with `-`. To add a
new rule, just put new values into `[appid|title]`.
To add support for new rules, you need to edit `fprintf` and `sscanf` calls in
`menurulefeed` and `menuruleaction` functions respectively.
For example, this is what I did to add support for [swallow][swallow] patch
rules.
