i3 feature support: Moving flotaing containers

This commit lets the 'move' command apply to floating containers as well
as tiled ones. The command may be appended with a number of pixels and
then optionally the string `px` (like '10 px') in order to move the
container more or fewer than the standard ten pixels.
