TBR: playground: namespace_browser: Move v.io/x/ref/tools to v.io/x/ref/cmd.

This is part of the v.io reorganization.  cmd is the standard
go directory for commandline binaries.  We actually have two:
cmd for regular command line tools, and services for servers.

Note, I am temporarily duplicating the vdl tool for ease of transition.
