[dwm] experimental layout patch

Hi,
I've patched dwm to have the client layout (tile mode) I wanted to have.
The new layout is like this:
(require monospaced font, see my wiki below in case gmail breaks my ascii art)

    |-- MASTERW --|

 - +-------------+-------+
 | | | |
    | | |
 M | | |
 A | | |
 S | | |
 T | M A S T E R | |
 E | | |
 R | | |
 H | +-------+
    | | |
 | | | |
 - +-------------+ |
    |.............| |
    |.............| |
    |.............| |
    |.............| |
    +-------------+-------+

I've added two shorcuts to make bigger or smaller the master window
(Mod-b and Mod-n)

If anyone is interested in giving it a try, feel free to clone my repo

(this patch also include my awk generator, see
http://wiki.mad.mw/WindowManager/dwm, to avoid re-configuring the C
code after every release w/out adding external configuration files)

saludos,
