major breaking change to import path for ki/ki

[Randall O'Reilly]

Last night I checked in a major breaking change to the import path for goki/ki -> goki/ki/ki — this was necessary for being able to include only ki/ki under gopy (goki/gopy is a fork of go-python/gopy that allows all of GoGi to be used under python).

In general we should always use this model of having no top-level code in a repository, and just stuttering with the main eponymous package as a subdir..

Also, after a few more fixes on gopy I’ll start working on the 3d part of goki/gi so that will become quite unstable — I’ll make a tagged version release prior to starting, once all the python side is fully working.
