Support changing the Command program

Since Command
mostly adheres to a builder pattern, and spawn
can be called multiple times, it would be useful to change the program.
Motivating example: a user wants to fall back to an less common filename or path in the case of a failure to spawn.
Proposed signature would look:
pub fn program<S: AsRef<OsStr>>(&mut self, program: S) -> &mut Command
Calling program
would imply calling arg0
.
It doesn't look like the effected filename
has a whole lot of other implications to worry about.
I could put together a PR for this if you're interested.
