[dwm] rpmohn patch set

Attached is my patch set for the dwm-0.7 source code. The functionality
modifications are described below. As a bonus, it uses fewer loc. If you
have similar itches, feel free to use my scratches!

* togglemax (MODKEY-m) works differently. Instead applying to a single
client and only while that client has focus, it applies to all clients
within the current tag view and remains in effect until you toggle it
off. The mode of each specific tag view is independent of all the other
tag views. In addition, you specify the startup mode for each tag view
within your config.h file. Look at the new tags[] definition in
config.default.h.

* togglemode (MODKEY-space) works differently. Instead of applying to
every client on every tag of the entire wm, it applies only to the
currently focused client. Floating clients are now always on top of
managed clients. You can also now use this toggle to put transient,
pop-up, or even rule-based floating clients into the managed, tiled
layout. Be aware that when you toggle a single client from managed to
floating, any remaining tiled clients in the tag view adjust because
there is one less client to tile. Floating clients are not affected by
togglemax. Remove the #define for DEFMODE from your config.h as it isn't
used with this patch set.

USAGE:
# patch <rpmohn-0.7.diff
Then configure and compile as usual.

TODO:
* Change max mode to stack mode.
