A new "put" mode is added to the pk command, so that the "pk put"
command can be used to create and upload blobs.
What this command does is actually just call the previously named
"camput" executable, which is renamed to "pk-put" in this change.
This involves adding a new way to register a mode in cmdmain, when such
a mode is just meant to call an external binary. To emphasize the
distinction, the existing func (to register a sub-command, or a mode) is
renamed from RegisterCommand to RegisterMode, and RegisterCommand is now
the name of the new func/way.

interestingly, I also discovered that GitHub will properly resolve links
that are relative to the root path (e.g. "/doc/foo")... it properly
rewrites these links to reference the named file relative to the
repository root.
also add a /doc/contributing.md file. This will never be served from
the website, since we have a redirect handler in place, but is added so
that we don't have broken links when browsing the docs on GitHub.
