Adding fullscreen mode to tabbed.

New windows should be in the foreground.

Changing the single-linked list for clients to a malloc()ed array. This makes
algorithms more efficient, that depend on the number of clients or shuffeling
around. The patch also adds new shortcuts to move tabs in their position. The
default color scheme is changed to the one of the maintainer.
