This commit adds a new component for communicating with mochad[1] a
socket interface for the CM15A and CM19A USB X10 controllers. This
commit leverages the pymochad library to interface with a mochad socket
either on a local or remote machine. Mochad is added as as a generic
platform because it supports multiple different classes of device,
however in this patch only the switch device implemented as a starting
point. Future patches will include other devices types. (although
that's dependent on someone gaining access to those)
