patch: columns

This patch adds an extra layout to dwm called col in which the windows
in the master area are arranged in colums of equal size. The number of
columns is always nmaster + 1, and the last column is a stack of
leftover windows just like the normal tile layout. It effectively acts
like the default tiling mode, except provides for vertical instead of
horizontal master windows.
