Update to 4.9:

4.9:
This release contains the ability to freely define various geometries
for the built-in layout algorithms in the config.h file. It also
contains some bugfixes and a polished code base.

4.8:
This version contains two new layouts, the horizontal tile layout
and the monocle layout. It also allows you more fine-grained control
of the bar position and layout areas due to the introduction of
several new variables that can be changed during runtime (if a
related function is implemented).
