Subject: [PATCH] Adding attachx patch (combined attach
 above/below/bottom/aside/master patch)

This includes the following attach modes:

0 - master (default behaviour): new windows become the new master
1 - attachabove: new window is placed above selected client
2 - attachaside: new window is placed on top of the stack
3 - attachbelow: new window is placed below selected client
4 - attachbottom: new window is placed at the bottom of the stack

Refer to:
