dashboard: rearrange tree, in prep for packagification

Package main binaries now go under cmd, leaving the top level for
similarly-named packages.

I'll be moving a lot of data structures and functions out of the
commands and into common packages.

A future CL will also unify all the "+build whatever" restrictions
into one common build tag, since there will be so much package sharing
coming up. Probably they will become "+build extdep", to indicate that
they have dependencies outside of x/tools.

 If you wish to run a Go builder, please email golang-dev@googlegroups.com first.
 There is documentation at https://golang.org/wiki/DashboardBuilders but
 depending on the type of builder, we may want to run it ourselves, after you
 prepare an environment description (resulting in a VM image) of it. See the env
 directory.
