[dev] [PATCH] [spacebed] movespace(): Move selected space instead of hubing

Before this pull request, movespace() just hubed positions of the selected space with
the new position. This resulted in unexpected behaviour when „moving“ a space over
one end of the list.

Now spaces are moved correctly by the specified amount of indizes.

Heyho,
In movespace() the current method is to hub two spaces with each other. If you
only use the +1 and -1 arguments from config.def.h, this works well and has the
expected effect in least cases. However when moveing a space over one end of the
list, it just gets hubed with the one on the other end of the list which is
surprising and strange if you expect the space to _move_ as the function suggests.
The following pull request fixes that by using memmove.
