Xpra: Ticket #1931: honour --start commands when attaching

It should be possible to execute new commands on a remote session when attaching. This would be even more useful when connecting via the proxy, where the remote sessions can be started empty.

The client should be able to run:

xpra attach --start=xterm

This should work equally well going through a proxy server:

xpra attach ssl://foo:bar@proxyhost/ --start=xterm

Done in r20046.

Note: the server must be started with --start-new-commands=yes.
