commands: Learn mouse_warping.

Place mouse at center of focused view when changing to a workspace on a
different output, if option is enabled. (This replicates existing i3
option.)

This can be triggered in multiple ways:
A) via `workspace <name>` which changes output
B) via `focus <direction>` which changes output
C) via `focus output <name>` which (obviously) changes output
