load scaled cursor theme with each output

turn focusnext into dwm's focusstack

restrict focusnext to the same monitor

style

add selclient() helper

This may get inlined later, but it's nice for now.  The focused client
if any should always be both at the top of fstack and visible on selmon.

continue to focus monitor under mouse cursor

focus monitor under mouse cursor initially

grabbed_client was too long a name

turn on some warnings

set normal and dwm-like defaults in config.def.h

move config.h to config.def.h

inline moveresize

There were only two lines left in common

grabsx/y are only used by move now

calculate resize based just on cursor/window

This eliminates the need for grab_height and grab_width.

add TinyWL and dwm LICENSE files

Credit where credit is due - dwl started with TinyWL and will be
including more bits of dwm code as it grows

add setlayout function

Don't change tiling order in focusnext()

Use the focus stack instead to determine which client is focused

add separate list of clients for focus order

Previously, clicking a client to focus it would change where it was in
the tiled layout as well.

layouts: tile and floating

Behavior's still a little wonky but positioning is there.

"root" color was easy to make configurable
