[xmonad] Several new modules (patch flood)

I apologize for the bulk delivery, these are all things I wrote over
the last week and I didn't really want
to stop coding to send updates (or eat, or sleep, for that matter --).
The basic idea was to implement the layout used in wmii. For those not
familiar with it:
- Windows grouped in resizable columns
- Each column has its own sub-layout, either full, vertical or
- You can of course move windows between columns, create new columns, etc.
This gave rise to a number of modules, which the rest of this mail describes.
To get a quick idea, you can also look at the few screenshots I put up:
A generic version of the wmii thing: windows arranged into groups,
each with its own sub-layout. You
provide both the (starting) layout for new groups, and the layout that
arranges the groups themselves
on the screen.
Tis doesn't fit XMonad's layout interface that well, and indeed I
ended up having to completely
decouple the layout's idea of window ordering from XMonad's. For this
reason, the usual
swapUp/Down and focusUp/Down don't work here; the Groups module
that can be used instead, and see #2 for a more flexible interface.
You can do a lot of fun things with the Groups combinator, so I put a
few examples in a dedicated
module. It also contains many useful X actions for Groups layouts,
swapUp/Down, etc. actions that work both for them and for standard
layouts (using X.A.MessageFeedback).
There are three example layouts:
- The wmii layout, pretty faithfully cloned with the exception that
I was too lazy to write a stacked
layout and used tabs instead. The columns are managed by a
ZoomRow (#3), so they can be
individually resized and/or maximized.
- A "row of columns" layout, with both rows and columns using ZoomRows.
- A "tiled tabs" layout that arranges windows into tabbed groups,
and the groups themselves
according to XMonad's default algorithm (Tall ||| Mirror Tall ||| Full)
A layout that arranges its windows into a horizontal row, and allows
to freely resize each of them
A LayoutModifier and DSL for modifying the description of a layout.
This is for when you want to
modify a layout with a dynamic description, and using Named would freeze it.
I ended up doing quite a bit of non-trivial (Maybe Stack)
manipulation, so I wrote a separate module
for that. It provides maps, folds, filters and the like, as well as the whole
focusUp/Down-swapUp/Down-insertUp/Down suite with consistent types.
I've been using these for a few pretty active days now but they are by
no means fully tested, feedback
